Answer:
1. 5
2. 5
3. -3
4.y= -1
5. 5
Step-by-step explanation:
1.)x- 2y= -25 ; y=3x
x-2(3x)=(-25)
x-6x=(-25) ; -5x=(-25) ; x=5
2.) 5x+3y =40; x=y
8y=40; y=5
3.) 4x-3y= -27; x=3y
4(3y)-3y= -27; 12y-3y=-27; 9y=-27; y=-3
4.)x-y=9; x=-8y; -8y-y=9; -9y=9; y=-1
5.) 2x+2y=30; y=2x ; 2x+2(2x)=30; 6x=30; x=5
16tbsp/1cup.
Multiply by 5 for 5 cups (I recommend cross multiplying with fractions)
80tbsp/5cups
Multiply by 1.25
20tbsp/1.25cups
Multiply by 2.7
43.2tbsp/2.7cups
Since you can’t have .2 of a table spoon, we need to round up.
44tbsp/2.7cups
Total tbsp:80+20+44tbsp=144tbsp
We would need 144 tablespoons for 8.95 cups (9 for the same reason that we rounded up with the table spoons)
The reasoning would be that it was given because there's no theorem or anything involved it was simply given to you already
The slope is-2/-2 because of the y and x axis
Answer:
1) -4
2) 2/3
Step-by-step explanation:
1) f(x)=x+4
*subtract 4 to both sides
x=-4
2) f(x)=3x-2
*add 2 to both sides then divide by 3*
x= 2/3
hope this helps :)
