\huge\boxed{ \sf{Answer}}

Given,

a = 5 \\ b = 4 \\ c = 7

And the equation we need to solve is,

3(b + a) = c

To find the answer, you need to substitute the values of a, b & c in the equation.

3(b + a) = c \\  3b + 3a = c \\  ( 3 \times 4) +( 3 \times 5) = 7 \\   12 + 15 = 7 \\ 12 + 15 - 7 = 0 \\  = 27 - 7 \\  = 20

↦ The answer is <u>2</u><u>0</u><u>.</u>

Answer:

7+(11-4\times 2)=10

Step-by-step explanation:

So, this question involves you to play around with the numbers and the operations a bit. I've come up with a solution, but perhaps there are others as well.

So, we have:

7\text{ } 11\text{ } 4\text{ } 2\text{ } =\text{ } 10

So, what we can do is, for instance, multiply 4 and 2. Subtract that into 11. And then add the difference to 7. Thus:

7+(11-4\times 2)=10

This is a true number sentence. Let's do it to make sure.

First, do the operations inside the parentheses.

Multiplication comes first, so multiply:

7+(11-8)=10

Again, do the parentheses first. Subtract:

7+(3)=10

Now add:

10=10

So our answer is correct :)

What is the equation of a line going through points (-15,70) and (5,10)
andrey2020 [161]
Simple....

you have:

(-15,70) and (5,10)

Using-->>

\frac{  y_{1} -y_{2} }{ x_{1}-  x_{2} }

\frac{70-10}{-15-5} = \frac{60}{-20} = -3

Using y=mx+b...and any of the coordinates....

70= -3(-15)+b

70=45+b

70=45+b
-45  -45

25=b

y=-3x+25

Thus,your answer.
