Answer:
Step-by-step explanation:
"Two times one number added to three times a second number is 21.
2x + 3y = 21
"The second number is ten less than five times the first number"
y = 5x-10
Substitution
2x+3(5x-10) = 21
2x + 15x - 30 = 21
17x = 51
x = 3
y = 5x-10 = 5
Answer:
2x+10
Step-by-step explanation:
to distribute you take the number on the outside of the parenthesis and multiply it with the individual values inside the parenthesis. So first you would multiply 2 times X which gives you 2x then 2 times 5 which gives you 10, then your answer would be 2x+10
Answer:
16 square inches.
Step-by-step explanation:
Split the shape into a rectangle and square. To solve for square, just mulitple the 2 sides (2 x 2) and you get an area of 4. To solve for the rectangle, you can multiple the 6 and 2 to get the area of 12. Add the 4 and 12 together and you get 16 square inches. Hope this helps!
