Answer:
4+3(7+4*2) - 100 = -51
Step-by-step explanation:
4+3(7+4*2) - 100
= 4 + 3 (15) - 100
= 4 + 45 - 100
= -51
Answer:
8x + 2y - 23
Step-by-step explanation:
(2y + 5) + (5x - 17) + (3x - 11)
2y + 8x + 5 - 17 -11
2y + 8x - 23
Answer:
726
Step-by-step explanation:
You multiply the base and the height (11x11) and multiply THAT by 6 because there are 6 faces on a cube.
Answer:
x = 14
Angle B = 121°
Angle C is 59°
Step-by-step explanation:
First we'll find x, then we'll find Angle B (by substituting in x), then we'll find Angle C (bc Angle B and C are supplementary--that us, they add up to 180°)
10x-19 = 7x+23 subtract 7x
3x-19 = 23 add 19
3x = 42 divide by 3
x = 14
Angle B is 10x-19, and if x=14, then its 10(14)-19
Angle B is 140-19
which is 121°
Angle B = 121°
Angle B and Angle C add up to 180°
121° + c = 180°
c = 180-121
Angle C is 59°
Answer:
Step-by-step explanation:
Steve and Elizabeth invest money in a 3:4 ratio, respectively. This means that Steve invests $3x and Elizabeth invests $4x.
They need $80,000 for the franchise, then
3x+4x=80,000,
7x=80,000
Thus, Elizabeth invests
