Multiply 3 with 7.
3 * 7 = 21
The value of the gift card changed by -$21 dollars.
Answer:
False
Step-by-step explanation:
5x - 2y + 1 > 0
plug in the given ordered pair x= -2 and y = -1:-
5(-2) - 2(-1) + 1
= -10 + 2 + 1
= -7 which is less than 0 therefore the answer is False
If b=2 and c=3, then
a= √(3²-2²) = √(9-4) = √5
If a=3 and c=6, then
b= √(6²-2²) = √(36-9) = √27 = 3√3
If a=4 and b=6, then
c= √(4²+6²) = √(16+36) = √52 = 2√13
Answer:
x = 2.5 or 5/2.
Step-by-step explanation:
They're congruent angle, so set them equal to each other
5x + 13 = x + 23
Solve for x:
4x = 10
x = 10/4 = 5/2 = 2.5
Answer:
16
Step-by-step explanation:
3 x 16 = 48
