Matthew counts his pennies. He has $4 worth of pennies.

How many pennies does Matthew have?

400

$1 = 100p

$1 x 4 = 100 x 4

= 400p

Would love a brainliest - just need one more to get to the next level!

Matthew has 400 pennies

Step-by-step explanation:

Because a penny is worth 1 cent, and in a dollar, there's 100 cents... then all you must do is multiply 4 by 100!

4 x 100 = 400

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
