x + 21 + 3x + 9 = 90
Combine like terms
4x + 30 = 90
Subtract 30 from both sides
4x = 60
Divide both sides by 4
x = 15
I believe 9, is it one of your options?
Answer:
24
Step-by-step explanation:
Since 15 tamales is $10, you can take 10/15 to get the price of one tamale, 0.67. Since you know the price of one tamale now, you can multiply 0.67*36 to get that 36 tamales is equal to $24
Perhaps you’ve written the answers out incorrectly. Answers A and B are the same.
The correct answer is:
y = -7x - 51
Answer: the same length for one of the other two legs.
It doesn't matter which leg since the triangles could be rotated. If the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, the two triangles are congruent.
