Answer:
B
X= 7.5
Y= -5
Step-by-step explanation:
In systems of equations, the goal is to add both of the equations together so it cancels one of the variables and you solve for that variable. Before you add they together, you multiply one of the equations by a negative number so when you add them together one of the numbers with x or y cancel.
I will upload a picture showing my work.
Change the percents to decimals (by moving the decimal 2places to the left)
(.24, .38)
Multiply each by 112,483.
(.24x112483, .38x112483)
(26,996, 42,744). You can’t have decimals because people are whole numbers. So round to the nearest whole number
Answer:
measure of angle A is 80 degree.
Step-by-step explanation:
isosceles triangle will have same base angles
first base angle is 50, and the second will also be 50
3 angles of a triangle will add up to be 180 degree.
A is the vertex angle.
So 50 + 50 + A = 180
100 + A = 180
A = 80.
Answer:
1 out of 9
Step-by-step explanation:
We can divide the shape into a rectangle and a triangle:
(1) Area of rectangle = length*width
From the graph we can see that the length of the rectangle is 7 units and the width is 5 units
Area = 7*5 = 35 units^2
(2) Area of triangle = 1/2*bh
From the graph we can see that the base of the triangle is 4 units and its height is 5 units
Area = 1/2*4*5 = 10 units^2
(3) Total area = area of triangle + area of rectangle
= 10 + 35
= 45 units^2
