Add 7 to both sides
At the left hand side 7 will cancel 7
At the right hand side 7 will add up
Divide through by 2
simplify the fraction
Answer:
15.60
Step-by-step explanation:
The sub total before tax is 34.95. You know the socks cost 3.75 and the skirt and shoes are the same or equal price. This means after subtracting the cost of the socks, you spent 34.95 - 3.75 = 31.20. Since the skirt and shoes cost the same, divide 31.20 by 2. This is $15.60.
If the slice is parallel to its base then it would be a rectangle also.
Answer:
y =52
Step-by-step explanation:
We know that the angles 4x and 5x make a straight line
4x+5x = 180
9x = 180
Divide by 9
9x/9 = 180/9
x = 20
The three angles of a triangle make 180
y + 48 +4x = 180
y + 48+4(20) =180
y + 48 +80 = 180
Combine like terms
y +128 = 180
Subtract 128 from each side
y + 128-128 = 180-128
y =52
I guess you want the measure of angle <CAB.
The angle ABD is flat thus its amplitude is 180 degrees. Because
<ABD = <ABC + <CBD you get
<ABC = <ABD - <CBD = 180° - 122° = 58°.
In a triangle, the sum of the amplitudes of the angles is 180°. Thus
<CAB + <ABC + <ACB = 180°. You get
<CAB = 180° - <ABC - <ACB = 47°.
