15x15= 225
15x + 105= 225
15x= 225-105
15x= 120
X=8
X+ (x+1) + (x+2) + (x+3)…etc all the way up too +(x+14)=225
The first five numbers of the set: 8, 9, 10, 11, 12
Answer:
550 + 70w = s
And
1880
Step-by-step explanation:
Let's write the equation.
550 + 70w = s
Now put in our value for w.
you multiply the 70 and 19 first, then add 550
550 + 70 · 19 = 1,880
The answers are
550 + 70w = s
And
1880
Answer:
x ≥ 27
Step-by-step explanation:
x/9 + 7 ≥ 10
Subtract 7 from each side
x/9 + 7-7 ≥ 10-7
x/9 ≥ 3
Multiply each side by 9
x/9 *9 ≥ 3*9
x ≥ 27
