I think the answer is D.Problem solving, including measurement and simple geometry problems
Let
x--------> amount of erasers that Sari has
y--------> amount of erasers that Sam has
we know that
-------> equation 
-----> equation 
Substitute equation in equation
![[3y]+y=28\\ 4y=28\\ y=28/4\\ y=7](https://tex.z-dn.net/?f=%20%5B3y%5D%2By%3D28%5C%5C%204y%3D28%5C%5C%20y%3D28%2F4%5C%5C%20y%3D7%20)
find the value of x
therefore
the answer is
Sari has 
erasers
First we need to find how far away the base of the ladder is from what it is leaning against. The ramp is the hypotenuse and the height from the ground in a leg. Let’s use Pythagorean’s theorem.
a^2 + b^2 = c^2
Substitute
a^2 + (5)^2 = (20)^2
Solve for a^2
a^2 = (20)^2 - (5)^2
Solve for a
a = 5 √15
The slope will be rise over run
5/5 √15 = √15/15 or 0.258…
Answer:
Step-by-step explanation:
$66.67/month for three months
The monthly payment is calulated by dividing the total cost of the mountain bike by 3. For example, if the total cost is $200, the three monthly payments will be $66.67 each:
$200
---------------- = $66.67/month for three months
3 months
Answer:
P(odd)- 1/2
P(even)-1/2
p(odd and then even=1/2*1/2)
= 1/4 or 25%
