7y - (4y - 14) = 23
---Distribute the negative sign into the terms in the parentheses
7y - 4y + 14 = 23
---Combine like terms
3y + 14 = 23
---Subtract 14 from both sides
3y = 9
---Divide both sides by 3
y = 3
Answer: y = 3
Answer Choice: A, 3
Hope this helps!
Answer:
A. The solution is y = 3.
Step-by-step explanation:
Given
7y - (4y - 14) = 23Distribute the value to the terms in parentheses.
7y - (4y - 14) = 237y - 4y + 14 = 23Simplify like terms and subtract 14 from each side.
3y + 14 - 14 = 23 - 143y = 9Divide by 3 on each side.
3y/3 = 9/3y = 3A. The solution is y = 3.

Step-by-step explanation:
Answer:
[tex]16ft \: ^{2} [/tex]
Step-by-step explanation:
To find the area of the given triangle we'll use the formula:-
[tex]\boxed{\sf A = \cfrac{1}{2} \times b \times h}[/tex]
Where,
Base(B):- 8 ftHight (H):- 4ft[tex]\sf A = \cfrac{1}{2} \times 8 \times 4[/tex]
First, let's multiply 1/2 * 8 = 8/2.
[tex]\sf \cfrac{8}{2} \times 4[/tex]Divide 8 by 2= 4
[tex]\sf 4 \times 4[/tex][tex]\sf 16[/tex]Thus, the area of the triangle is 16ft^2.

HII GIVING BRAINLIESST TO WHO EVER EXPLAINS AND HELPS ME THANK U
Step-by-step explanation:
we don't need to actually do the detailed area calculation.
all we need to consider is that an area, ANY area (for triangles, rectangles,...) is always the product or the sum of products of 2 dimensions (like side lengths).
the scaling factor of similar objects (incl. triangles of course) applies to each individual line, length, height or side.
so, when calculating the area of a similar figure, the scaling factor has to be multiplied in twice (once for every multiplied dimension) - making it the square of the normal single-dimensional scaling factor.
so, in other words, the area scaling factor is the square of the side scaling factor.
coming from A1 to A2 the area scaling factor is
80/45 = 16/9
the side scaling factor is then
sqrt(16/9) = 4/3
we have to multiply a side of A1 by 4/3 to get the corresponding side of A2.
and so, the ratio of A1 side lengths to A2 side lengths is
3:4
(the inverse, upside-down form of the scaling factor as a consequence of the question "how do I convert the 3 length units of A1 into 4 length units of A2 ?" by multiplying the 3 units by the scaling factor 4/3).

What is ∑n=15[5(−2)n−1] equal to?
Answer:
Although the notation is sloppy, I will assume based on former questions of the same that "∑n=15[5(−2)^n−1]" translates mathematically to . Please correct me, though, if this in incorrect.
Anyway, there is neat formula that will deal with question very quickly. It is the following:
Sn is the sum of the geometric series
a1 is the first term in the series
r is the common ratio
n is the number of terms in the finite geometric series
Let's use this formula to our advantage! However, there are two variables that we do not know: a1 and n. Let's start with a1.The first term in the series is when n=1, so let's determine what that is.
The expression ∑n = 15 [5 (−2) n − 1] is equal to 5/16384.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
First, let's understand the notation.
∑n = 15 represents the sum of the expression that follows for n starting from 15, and the expression is 5 (−2) n − 1.
So, we need to find the sum of 5 (−2) n − 1 from n = 15 to n = 15, which means there is only one term in the sum.
Substituting n = 15, we get:
5 (−2) (15 − 1) = 5 (−2) 14 = 5/16384
Therefore,
The expression ∑n = 15 [5 (−2) n − 1] is equal to 5/16384.

You start at (3, -2). You move up 5 units. Where do you end?
Answer:
You would end at (3, 3).
Explanation:
You would plot your first mark at 3 on a typical xy graph because the first number in ()'s is always x (horizontal line).
Second, because your second mark is y (vertical line), you would plot -2 on the vertical axis.
Your y plot would be 5 more than -2 because you're traveling up five units, giving you (3, 3).

What is multiplication?Multiplication is when you take one number and add it together a number of times.
Example: 5 multiplied by 4 = 5 + 5 + 5 + 5 = 20. We took the number 5 and added it together 4 times. This is why multiplication is sometimes called "times".
Given that are four multiplication, 10000x30, 1000x30, 100x30 and 10x 30,
We know,
Multiplication by multiples of 10, 100, 1000, 10000:
We multiply the multiplicand by the non-zero digit of the multiplier. Then we add the same number of zero to the extreme right of the product as the multiplier has.
For example :-
26 × 10000 = 260000
524 × 10000 = 5240000
Therefore,
10000 x 30 = 300000
1000 x 30 = 30000
100 x 30 = 3000
10 x 30 = 300
Hence, the product of the given multiplications are 300000, 30000, 3000 and 300

Also, pi (π), which is a mathematical constant. The letters phi (φ) and theta (θ) are also used for angles very often, especially in formulas. You'll see some of these in physics too.

so first lets see how much he saved
0.45(60) = 27
he saved 27 dollars so far. to find how much more he has to save, you have to do the amount he needs minus the amount he already has

What is a line segment?In Mathematics, a Line Segment is a part of a line that has two endpoints.

Note that if QS is Parallel to TV, then both sides of the triangle must be proportionally divided by TV.
That is: RV/VS = RT/TQ.
Step 2 - replace the segments by the relevant equations
(X + 4)/(X- 3) = (X+10)/(X)
Step 3 - Cross Multiply
x(x +4) = (x -3)(x +10)
Removing the parentheses, we have
X² +4X = X² +7X -30; Subtract X² from both sides and we have;
4X = 7X - 30
Step 3 - Collect like terms by cross multiplying-3X = -30 or

The sum of two numbers is 36. One number is 2 times as large as the other. What are the numbers?
Larger number:
Smaller number:
Let the first number be "x", and the 2nd number (which is twice as large as the other), be 2x.
Set the equation
2x + x = 36
Simplify. Combine like terms
(2x + x) = 36
3x = 36
Isolate the x. Divide 3 from both sides
(3x)/3 = (36)/3
x = 36/3
x = 12
The first number is 12
The second number is 2x. Replace x with 12. Multiply.
2x = 2(12) = 24
