Answer:
Step-by-step explanation:
Sweet. Get to answer finally. I was the guy commenting on your other post.
1. 72
2. 46
3. 99
4. Same side interior angles are supplementary
5. alternate interior angles are equal to each other so set up the x expressions equal to each other. 5x-7=3x+17. Solve for x
5x-7=3x+17
2x=24
x=12
plug it in for the 5x-7 and get an angle.. 5(12)-7
60-7
53.
The 5x-7 and the 4y+3 is supplementary.
so 53+3+4y=180. combine the 2 and set them equal to 180 to find y
56+4y=180
124=4y
y=31
And now we find the angle of 6. We know that corresponding angles are equal and the y expression and angle 6 are corresponding angles
so plug in your answer for y in the expression..
4(31)+3 = 127.
so angle 6 is 127
Answer:
9 large apartments in B
Step-by-step explanation:
Same ratio
Building A = 12 small : 6 large
= 2 : 1
Building B = 18 small : x large
= 2 : 1
18/x = 2/ 1
18 = 2x
9 = x
Large apartments in B = 9
Ok we need a common coefficient of either x or y:
12x+21y=3
12x+40y=60
We can subtract one from the other to get:
19y=57
Now divide by 19 to get:
y=3
Now if we sub this back in we see that:
3x+30=15
3x=-15
x=-5
Answer:
(5, 2)
Step-by-step explanation:
Answer:
The width is 10cm and the length is 50cm.
The top and bottom sides are each 50 cm, and the right and the left side of the rectangle is 50cm. Which means, if you multiply 50 by two, and 10 by two, then add them together, you will get the perimeter of 120 cm. Formula of Perimeter: Length + Length + Width + Width = Perimeter
I found the answer by multiplying the width (10cm) by 2. I then got 20. After that I subtracted 20 from the perimeter and got 100. Then, I divided that by 2 and got the length of each of the sides which is 50cm.
