A rectangular pyramid has a base that is a rectangle, but comes up into a point.
Answer:
x=-5, y=-5. (-5, -5).
Step-by-step explanation:
-x-5y=30
10x+5y=-75
------------------
9x=-45
x=-45/9
x=-5
-(-5)-5y=30
5-5y=30
5y=5-30
5y=-25
y=-25/5
y=-5
Answer:
Simon's Age = 47
Marcie's Age = 11
Step-by-step explanation:
<em>The question is to find Simon's age and Marcie's age.</em>
<em />
Let Simon's age be x and Marcie's age be y
<u>Simon is 3 years more than 4 times marcie, so we can write:</u>
x = 4y + 3
Also,
<u>Sum of their ages is 58, so we can write:</u>
x + y = 58
or x = 58 - y
Now, we substitute this into 1st equation and solve for y first:
We know
x = 58 - y
so,
x = 58 - 11
x = 47
So,
Simon's Age = 47
Marcie's Age = 11
Answer:
16/3 or 5.3
Step-by-step explanation:
150 miles = 4 hours
Find how long it takes to travel 50 miles(GCF between 150 and 200)
150/3 = 4/3
50 miles = 1 1/3 hours: multiply by 4 to get 200 miles
50 x 4 = 4/3 x 4/1
200 = 16/3
16/3 hours or 5.3
