consider this expression: 7(10a+3b)
enter and expression that shows the sum of exactly two terms that are equivalent to 7(10a+3b).

70a + 21b

Step-by-step explanation:

By The Distributive Property, we can multiply a sum by multiplying each addend separately and then add the products,

That is, a(b+c) = ab + ac,

Here, the given expression is,

7 (10a + 3b),

By the above property,

We can write,

7 (10a + 3b) = 7 × 10a + 7 × 3b = 70a + 21b

Where, 70a and 21b are two different terms,

Thus, the required expression is 70a + 21b.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
