Answer:
Step-by-step explanation:
<u>Scale is:</u>
- 1 foot = 3/4 inch
- 1 inch = 1 : 3/4 foot = 4/3 foot
a. The length of the room
- 9 inches = 9*4/3 foot = 12 feet
b. The width of the room
- 6 3/4 inches = 27/4 inches = 27/4*4/3 = 9 feet
Answer:
Perimeter= 44.2 inches
Area= 70 inches squared
Step-by-step explanation:
Perimeter- Add all your sides together (10+ 17.2+2+3+7+5=44.2)
Area- 1/2bh (b=base, h=height)
Your base is the bottom of the triangle, so 2+7+5=14.
14 is your base
Your height is the 10
1/2 *14*10
1/2 of 14 is 7
7*10= 70
Don't forget to write inches squared or it will be wrong

The equation would be
x * -7 = 63
To solve it you would divide by -7 on both sides.
x * -7 / -7 = 63 / -7
x = -9
Answer:
y=1/3x+5
Step-by-step explanation:
I believe this question is turn in to slope-intercept form. If it's not, please let me know. So slope-intercept form is y=mx+b and on the question, they use standard form. Standard form is Ax+Bx=C. To turn standard form into slope-intercept form, you simply make you're y value alone on one side. So you're going to move x to other side my subtracting x on both sides. -3y=-x-15. Right now, we are almost done. We just have to make y own their self which means that y must me one. To make it as one, you will divide -3 on both sides. y=1/3x+5. Make sure in this step, you have to look very careful with negative numbers. If you multiply or divide negative number to negative number, it turns in the positive. So x-3y=-15 is equal to y=1/3x+5.
