Answer: 873
Step-by-step explanation:
let age = x
x/3 - 76 = 215
x/3 = 291
x = 873
Answer:
1. -3
2. 7
3. -2
4. 3
Step-by-step explanation:
1. idk
2. 3.2 move 3b over to get 3.2-3b-4.7=-3.3 move 4.7 over to get
3.2b-3b=4.7-3.3 now 3.2b-3b=.2b and 4.7-3.3=1.4 .2b/.2=b 1.4/.2=7 so b=7
3. 4.6y-y+4=y-1.2 now switch the 4 and the y to read 4.6y-2y=-4-1.2
2.6y=-5.2 divide both sides by 2.6 to get y=-2
4. 7.5c-2.5c+8=-7 move 8 to other side to get 7.5c-2.5c=-8-7
5c=-15 divide both sides by 5 getting c=3
Slope is 4/3
y-intercept is -8/3
Answer:
Equation: 2x + 5 + 6x + 15 = 92
Solution: x = 9
m∠A =23° m∠B = 69°
Step-by-step explanation:
measure of ∠B = 3(2x + 5) = 6x + 15
The sum of the angles = 92 = 2x + 5 + 6x + 15
92 = 8x + 20
72 = 8x
x = 9
m∠A = 2(9) + 5 = 18 + 5 = 23
m∠B = 6(9) + 15 = 54 + 15 = 69
Check: 23 + 69 = 92 and 23(3) = 69
