Answer:
Ratio of Wood MS to Parker MS = 81 : 131
Step-by-step explanation:
Given
number of students at WMS = 136+188 = 324
number of students at PMS = 316+208 = 524
Ratio of students
WMS : PMS = 324 : 524 = 81 : 131
There are 11 skateboards and 9 bikes.
Set up your equations: 4s+2b=52 and b+s=20
Multiply the 2nd by 2, 2b+2s=40
Subtract the second equation from the first
2s=22
so 11 skateboards and 9 bikes
Answer:
<C = <A
Step-by-step explanation:
In parallelograms, opposite angles are congruent. This means that <C=<A and <B=<D. Additionally, adjacent angles are supplementary; so when added they equal 180.
Answer:
Option 1: 2x + 11 = 90.
x = 79/2 or 39.5 degrees
Step-by-step explanation:
Option 1: You know that the angle for option one is 90 degrees because of the marking. Since you know that part of the angle is 11 degrees, you can set up an equation for 2x + 11 which equals to 90 degrees.
