David made 30 cups of tea per hour. David worked for D hours. In D hours, he made 30D cups of tea. Then he made an additional 10 cups of tea, so this week, he made 30D + 10 cups of tea.
Andrew made 35 cups of coffee per hour. Andrew worked for A hours. In A hours, he made 35A cups of tea.
The total cups of tea and coffee made this week is:
30D + 10 + 35A
4(x - 3) + 5 = 1....distribute thru the parenthesis
4x - 12 + 5 = 1....simplify
4x - 7 = 1...add 7 to both sides
4x = 1 + 7...simplify
4x = 8...divide both sides by 4
x = 8/4
x = 2 <===
Answer:
x = 26
Step-by-step explanation:
The midsegment is parallel to the side KM and half its length, thus
KM = x = 2 × 13 = 26
Add the exponents since it’s multiplication, so it would be 2a^7, hope this helps
