So 110% of x is 880 means 1.1x=880
so 1.1x=880
multiply both sides by 10
11x=8800
divide both sides by 11
8800=88 times 100 88=8 times 11
8800/11=800
x=800
X=7. The two segments on the bottom as well as on the diagonal are the same length. This shows that the entire triangle and the inner triangle on the right are similar. So if we call the length of the bottom 2y, then 84/2y=6x/y. Solving this we get 84=12x, and so x=7
Answer:
109
Step-by-step explanation:
81-19 is 62. if you add 109 then you could do 109-19 is 90
10
because you would do 35 divided by 7 which is 5.
5 x 2 is 10
Answer:
-5 =x
Step-by-step explanation:
3^(x-1) = 9^(x+2)
Replace 9 with 3^2
3^(x-1) = 3^2^(x+2)
We know that a power to a power means the powers are multiplied
a^b^c = a^(b*c)
3^(x-1) = 3^(2x+2)
When the bases are the same, the powers have to be the same
x-1 = 2x+4
Subtract x from each side
x-x-1 =2x-x+4
-1 =x+4
Subtract 4 from each side
-1-4 =x+4-4
-1-4 = x
-5 =x
