Suppose x = 7 is a solution to the equation 4x - 2(x + a) = 8. Find the value of a that makes the equation true
Answer:
[tex]a=3[/tex]
Step-by-step explanation:
So we have the equation:
[tex]4x-2(x+a)=8[/tex]
And we want to find a such that x = 7 is a possible solution.
To do so, substitute 7 for x. Thus:
[tex]4(7)-2(7+a)=8[/tex]
Multiply the left and distribute the right:
[tex]28-14-2a=8[/tex]
Subtract:
[tex]14-2a=8[/tex]
Subtract 14 from both sides:
[tex]-2a=-6[/tex]
Divide by -2: "
[tex]a=3[/tex]
So, the value of a is 3.
And our equation would be:
[tex]4x-2(x+3)=8[/tex]
And we're done!

Mikel gave a \$1.32$1.32dollar sign, 1, point, 32 tip for an order that cost \$8.80$8.80dollar sign, 8, point, 80. Determine whether or not each tip below is proportional to Mikel's tip.
Answer:
The question is incomplete, below is a possible match for the complete question:
Mikel gave a \$1.32$1.32dollar sign, 1, point, 32 tip for an order that cost \$8.80$8.80dollar sign, 8, point, 80. Determine whether or not each tip below is proportional to Mikel's tip. Proportional to Mikel's tip Not proportional to Mikel's tip
1.) \$2.22$2.22dollar sign, 2, point, 22 tip for a \$14.80$14.80dollar sign, 14, point, 80 order
2.) \$1.86$1.86dollar sign, 1, point, 86 tip for a \$10.50$10.50dollar sign, 10, point, 50 order
3.) \$0.78$0.78dollar sign, 0, point, 78 tip for a \$5.20$5.20dollar sign, 5, point, 20 order
Answers
1) proportional to Mike's tip
2) Not proportional to Mike's tip
3) proportional to Mike's tip
Step-by-step explanation:
when two things have the same relative sides, they are said to be proportional.
To determine if the other tips are proportional to Mikel's tip, we will, first of all, determine the size of Mikel's tip, then compare the other tips with it.
Mikel's tip:
$1.32 for $8.80
= [tex]\frac{1.32}{8.80}= 0.15[/tex]
Now, let us compare this with the other tips
1.) $2.22 for 14.80
= [tex]\frac{2.22}{14.80} = 0.15[/tex]
proportional to Mike's tip
2.) $1.86 for $10.50
[tex]\frac{1.86}{10.50} = 0.177\\0.177 \neq 0.15[/tex]
Not proportional to Mike's tip
3.) $0.78 for $5.20
= [tex]\frac{0.78}{5.20} = 0.15[/tex]
proportional to Mike's tip

PLS HELP NEED ASAP The formula d=rt gives the distance traveled for a rate r and an amount of time t. A car travels at a rate of 60 miles per hour for 3 hours. What distance did the car travel? 20 miles 57 miles 63 miles 180 miles
Distance = rate x time
Distance = 60 x 3
Distance = 180 miles.
Answer:
180m
Step-by-step explanation:
d= distance traveled => ?m
r= rate => 60m/h
t= time => 3h
Formula=> d=r.t
>d= 60 x 3=> d= 180m
So
d= distance traveled => 180m
r= rate => 60m/h
t= time => 3h
If the domain of a function that is translated up 5 is (-1,8), (-2,4),(-1, -7),
what is the range?
O (-1,3), (-2,-1),(-1,-12)
O (-6,8).(-7,4), (-6, -7)
O (5,8), (3,4),(4,-7)
0 (-1, 13), (-2,9),(-1,-2)
Answer:
The right answer is 0 (-1, 13), (-2,9),(-1,-2).
Step-by-step explanation:
if (-1,8), (-2,4),(-1, -7) has already translated the domain, then all you need to do is add 5 to every range in the relation. To which will become (-1, 13), (-2,9),(-1,-2) .

Convert 334° to radians. A) 167π 45 B) 167π 50 C) 167π 90 D) 167π 100
Answer:
The answer is option CStep-by-step explanation:
To convert an angle from degrees to radians multiply the number by
[tex] \frac{\pi}{180} [/tex]To convert 334° to radians multiply it by the value above
That's
[tex]334 \times \frac{\pi}{180} \\ = \frac{334\pi}{180} [/tex]We have the final answer as
[tex] \frac{167\pi}{90} [/tex]Hope this helps you

8x - 3 = 3x + 2
A. One solution
B. Infinite solutions
C. No solutions
please explain how you got it
A one solution because it's x=1
Step By Step explanation:this is the original problem
8x-3=3x+2
we want to have x by itself so. . .
we add three on both sides. it cancels -3. And 2+3=5
8x=3x+5
we subtract 3x on both sides so 8x-3x=5x and 3x cancels on the other side
5x=5
we divide by 5 on both sides to get x by itself
x=1
if it was 1=1 or x=x (the same on both side) it would've been infinite solutions. if the numbers didn't match like 4=6 it would've been no solution

what is the greatest common factor of 8 and 16
Answer: 8
Step-by-step explanation: Usually you should use prime factorization or the “ladder” method; however, with questions like this that have small, easy numbers, you can simply think about it. Every number’s largest factor is itself, which means that 8 is at least a factor of 8. We also know that 8 times 2 equals 16, hence, the greatest common factor is 8.
Which two numbers does the square Root of 52 lie between on a number line?
Answer:
between 7 and 8
Step-by-step explanation:
7 squared is 49
8 squared is 64
49 < 52 < 64
The perimeter of a square is 64 mm. Write and solve an equation to determine the length of each side of the square.
Answer:
64/4=16
Step-by-step explanation:
a square has 4 equal sides so you divide the perimeter by 4 and that will get you the length of one side.

Answer: 4 3/8 ≈ 4.38
Step-by-step explanation:
To start off, note that 4 3/8 is a mixed number, also known as a mixed fraction. It has a whole number and a fractional number. We have labeled the parts of the mixed number below so it is easier to follow along.
4 = Whole number
3 = Numerator
8 = Denominator
To get 4 3/8 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.Step 1: Multiply the whole number by the denominator:
4 × 8 = 32
Step 2: Add the product you got in Step 1 to the numerator:
32 + 3 = 35
Step 3: Divide the sum from Step 2 by the denominator:
35 ÷ 8 = 4.375
That's it folks! The answer to 4 3/8 in decimal form is displayed below:
4 3/8 ≈ 4.38

Which point is an x-intercept of the quadratic function f(x)=(x-8)(x+9)
Step-by-step explanation:
An x-intercept of a function occurs when f(x) = 0.
In f(x) = (x-8)(x+9), f(x) will be 0 if either (x-8) is 0 or (x+9) is 0.
Hence, f(x) = 0 when x = 8 or x = -9.
