Answer:
j-128
Step-by-step explanation:
just add the number so you do
j+16-148=4
We move all terms to the left:
j+16-148-(4)=0
We add all the numbers together, and all the variables
j-136=0
We move all terms containing j to the left, all other terms to the right
j=136
Answer:
j= -128
Step-by-step explanation:
Write an equation of the line that is perpendicular to 2x +4y = 6 and passes through the point (6,4)
Answer:
B
Step-by-step explanation:
let equation be y = mx + b.
2x + 4y = 6
1/2x + y = 3/2
y = -1/2x + 3/2
since perpendicular, their gradients produced equals neg 1.
so,
m = -1/(-1/2) = 2
sub (6, 4):
4 = 2(6) + b
b = -8
therefore, eqn is y = 2x - 8

Mia has some beans that weigh 91 grams and some rice that weigh 58 grams how much more do the beans weigh then the rice?
Answer:33
Step-by-step explanation: Subtract 91 by 58
After that it gives you 33 so the beans weigh 33 more g's than the rice
Answer:
The beans weigh 33 grams more than the rice.
Step-by-step explanation:
To solve this, find the difference between the two numbers by subtracting the smaller number from the larger one.
91-58=33
what is the value of angle s
Answer:
54
Step-by-step explanation:
As we know s+19+(180-73)=180
so s+19=73
s=54
Please helppp it’s confusing!!!
Answer:
First you'd look at PEMDAS (parenthesis, exponent, multiplication, division, addition, and subtraction( you'd look at them in this order to solve the equation properly.))
So there is a parenthesis, that would be the 3(2^0). ignore the three, because you're focusing on the parenthesis. Any number other than zero with an exponent of zero will always be one. leaving you with 3(1).
So by now you should know (depending on your level of mathematics, That a number beside a single number in a parenthesis is multiplication. so 3 times 1.
Knowing that any number, other than zero, multiplied by 1 is the number itself, The answer is 3
In short, 3(2^0) = 3

Answer: ∠1 = 77; ∠3 = 41; ∠5 = 41; ∠6 = 92; ∠9 = 103; ∠12 = 47; ∠14 = 103; ∠17 = 41
because of 2 parallel lines
=> ∠1 = ∠10 = 77°
∠7 = ∠12 = 47°
∠16 = ∠7 + ∠6 = 139° ⇒ ∠6 = 139° - ∠7 = 92°
have: ∠7 + ∠6 + ∠5 = 180° ⇒ ∠5 = 180° - (∠7 + ∠6) = 180° - 139° = 41°
∠10 + ∠14 = 180° ⇔ ∠14 = 180° - ∠10 = 103°
∠14 = ∠9 = 103°
∠3 = ∠5 = ∠17 = 41°

On Roberto’s shelf he has 6 mystery books, 5 science fiction, 4 history and 3 adventure. Roberto will randomly choose 1 book to read. What is the probability that he will choose an adventure book?
Answer:
3/18, or simplified, he has a 1/6 chance of grabbing an adventure book.
Step-by-step explanation:
6 + 5 + 4 + 3 = 18. There's 3 adventure books, which makes it so that he has a 3/18 chance of it being an adventure book. How did I simplify? 18 ÷ 3 = 6, 3 ÷ 3 = 1.

HELP ME PLS IM STUCK HELLA AND ITS WRONG WHICH ONES RIGHT
Answer:
It is e = 3
Step-by-step explanation:
It is e = 3 and not e = -3 because 44e - 41 e = 3e, then you'd subtract 30 from both sides to get the 3e equal to something which is 9. then dividing both sides by 3 would give you e = 3

A collection of nickel and quarters is worth $4.65. There are 3 more nickels than quarters. How many coins are there in the collection?
Answer:
There are 15 quarters and 18 nickles
Step-by-step explanation:
The equations derived from this word problem are
5n + 25q = 465
and
3 + q = n
Fill (3 + q) into n in the first equation then solve. You get q = 15.
Then plug 15 into second equation (cause it's easier).
You get n = 18

Consider the right triangle below.
6x - 44
2x - 20
3x + 24
If the perimeter of the triangle is 224 cm, find the area of the triangle.
The area of the triangle is
cm
Answer:
Area = 1,344 cm²
Step-by-step explanation:
First, find the value of x and the numerical side length of all sides of the triangle before finding the area.
Thus:
Perimeter of a triangle = sum of all its side
Therefore,
(6x - 44) + (2x - 20) + (3x + 24) = 224
Solve for x
6x - 44 + 2x - 20 + 3x + 24 = 224
Add like terms
11x - 40 = 224
Add 40 to both sides
11x = 224 + 40
11x = 264
Divide both sides by 11
x = 24
Find the measurement of each side length by plugging in the value of x:
Hypotenuse = 6x - 44 = 6(24) - 44 = 100 cm
Height = 2x - 20 = 2(24) - 20 = 28 cm
Base = 3x + 24 = 3(24) + 24 = 96 cm
Find the area:
Area = ½×base×height
Plug in the values
= ½×96×28
Area = 1,344 cm²
