Answer:

1/4x - 3 = 12

Step-by-step explanation:

When it says "three fewer," it means subtract three from one fourth of x. "Is" always means the equal sign. Knowing this, we get the equation:

1/4x - 3 = 12

The sum of two numbers is 79. Three

Semmy [17]

Answer:

The two numbers are 23 and 56

Step-by-step explanation:

Let's say the two numbers are A and B.

We are told:

1) A+B=79

2) 3A+5B=283

Let's take the first expression and solve for A:

A+B=79

A=79-B

Now use this value of A in the second expression:

3A+5B=283

3(79-B)+5B=283

237-3B+5B=283

2B = 46

B = 23

Since B=23, we know from 1) that

A+B=79

A+23=79

A = 56

CHECK:

Does A+B=79?

56+23 = 79? YES

Does 3A+5B=283?

3(56)+5(23)=283

168 + 115 = 283? YES

liberstina [14]

Answer:

Step-by-step explanation:

1. Find the slope:

7 -3/ 1 + 1 = 4/2 = 2 = m

2. Find b by plugging in the m and one of the points given into y = mx + b

7 = 2 ( 1 ) + b

7 = 2 + b

5 = b

3. Write the equation using the m and the b you just found

y =2 x + 5
