Answer:
12
Step-by-step explanation:
10x-11+3x-2+3x+1=180
16x-12=180
16x=192
x=12
First off Jackson's mom sucks for limiting game time and second of the answer is 30 minutes. If 9 is 30 percent that means 3 is 10 percent. 3 times 10 is 30. So 30 minutes
Answer:
$15.00
Step-by-step explanation:
Suppose 1 rose bush costs r dollars,
Suppose 1 geranium costs g dollars.
Here are 2 equations:
1)6r+14g=146
3r+7g=73
2)r+7g=57
r=57-7g
Put 2) in 1)
3(57-7g)+7g=73
171-21g+7g=73
98=14g
g=7
r=8
7+8=$15.00
Hope I helped!
1.7/1.9 = 0.894 (rounded)
For this case we have the following solution.
x = gallons of water to be added
For the 10% solution we have:
0.1 * 8 = 0.8
Then, for 5% we have:
(0.8 / x + 8) = 0.05
Rewriting:
(0.8 / x + 8) = (5/100)
Answer:
An equation can be used to find x, the humber of gallons of water he should add is:
(0.8 / x + 8) = (5/100)
