Let the first number be x
1st number = x
2nd number = x + 2
3rd number = x + 4
4th number = x + 6
5th number = x + 8
x + x + 2 + x + 4 + x + 6 + x + 8 = 120
5x + 20 = 120
5x = 100
x = 20
3rd number = x + 4 = 20 + 4 = 24
Answer: 24
Answer:
y= -576
Step-by-step explanation:
y=j(11+k)^2
^=exponent
j=-4
k=1
Replace the variables with the numerals
y= -4(11+1)^2
y= -4(12)^2
Do 12^2 (a.k.a 12x12)
y=-4(144)
y=-576
hope this helps
Answer:
1. a. 544%
b. 84%
2. 175
3. $867.18
Step-by-step explanation:
1. a.2.32-0.36=1.96
1.96/0.36=5.44
5.44*100=544
b. 1.96/2.32=0.84
0.84*100=84
2. let x = # of 7th graders
let y = # of 8th graders
y is 125% of x
y=1.25x
x=140
y=1.25*140
y=175
3. A=P(1+r)^t
A=700(1+0.055)^4
A=867.18
