If you do 1800 divided by 300, the answer is 6 hours
Answer:
x = -2
Step-by-step explanation:
5x + 2(x - 4) = 5x + x - 10
→ Expand the brackets
5x + 2x - 8 = 5x + x - 10
→ Collect the x terms
7x - 8 = 6x - 10
→ Minus 6x from both sides
x - 8 = -10
→ Add -8 to both sides
x = -2
12-(x+3)=10
Simplify the equation.
12-x-3=10
Combine like terms.
(12-3)-x=10
Simplify.
9-x=10
Subtract 9 from both sides to get x by itself.
-x=1
Divide both sides by -1 to get x by itself.
x=-1

Answer:
<u>There are 350 girls in the school.</u>
Step-by-step explanation:
1. Let's review all the information provided for answering the question correctly:
Ratio of number of boys to the girls = 5:7
Number of students in the school = 600
2. How many girls are there in the school?
Number of girls = x
Number of boys = 5/7x
x + 5x/7 = 600
7x + 5x = 4,200
12x = 4,200
x = 350
<u>There are 350 girls in the school.</u>
And the number of boys is (600 - 350) = 250.
YZ = 16. The triangles are congruent. This would be AAS so YZ = 16 because of CPCTC.
