Can someone help with this question please

Input: -7

Step-by-step explanation:

We need to make an equation before solving for x, the input.

Output of A: x × 5 - 4 = 5x - 4

Output of B: x × 3 + 8 = 3x + 8

You know that the output of A is three times the output of B:

5x - 4 = 3(3x + 8)

Now that we have an equation, we can work out the value of x.

5x - 4 = 9x + 24

Isolate like terms.

-24 - 4 = 9x - 5x

Evaluate.

4x = -28

Find x.

x = -28 ÷ 4

x = -7

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
