Answer:
Step-by-step explanation:
Write an equation:
Solve for x:
Divide by 55:
In similar triangles ratios of the corresponding sides are constant,
so
6/4=4.5/n ----> n=4*4.5/6 = 3.0
n=3.0
6/4 = m/5
m=6*5/4=7.5
m=7.5
20*1.95 =39 girls
26girls/39girls =0.667
0.667*100 = 66.67%
Answer:
12 days
Step-by-step explanation: if he drinks 1 cup each day and he has 12 cups of juice then 12 cups equals 12 days
To solve this problem you must apply the proccedure shown below:
1. You have that the the polynomial being subtracted is 0.6t²+8-18t, therefore, <span> to find the additive inverse of the polynomial, you must multiply it by -1, as following:
</span>(0.6t²+8-18t)
(-1)(0.6t²+8-18t)
2. Therefore, you obtain the following result:
-0.6t²-8+18t
Then, tas you can see, the answer is -0.6t²-8+18t.
