Answer:
3/8 inches
Step-by-step explanation:
The postcard must be less than 4 1/2 inches high.
Elayne's postcard is 4 7/8 inches high.
We need to subtract the limit from the height of her postcard to know how high it is above the limit:
4 7/8 - 4 1/2 = 3/8
Her postcard is higher than the limit by 3/8 inches.
Colorado and Boston have 263 and 219 days of sunshine respectively.
<h3>
What is the solution to the Equation?</h3>
Let the number of days of sunshine in Colorado is x and the number of days of sunshine in Boston is y.
Total number of days of sunshine=482
Also, the number of days of sunshine in Colorado is 1.2 times the number of days of sunshine in Boston.
So, the equation is formed as follows:
x+y=482 -(1)
The other equation is formed as:
x=1.2y -(2)
Substitute the value x from equation (2) in (1),
1.2y+y=482
2.2y=482
y=482/2.2
y=219
Substitute the value of y in equation (1),
x+219=482
x=482-219
x=263

488cm² is your answer
Step-by-step explanation:
the area of the composite figure=area of rectangle +area of triangle
=l×b+1/2 b×h=17×22+1/2×{22-10}×19 =488cm²
Solve for one variable x or y first. So lets solve for x. If you take the first equation x= -12 -5y. You then plug that into the second equation
5(-12-5y) +4y = 24
now you solve for y
-60 - 25y + 4y =24
-21y=84
y=-4
Now you plug in y back into either equation and you get x=8
