Answer:
x=-5 y=6
Step-by-step explanation:
y-3x=21
y-3x+3x=21+3x
y=3x+21
x-5y=-35
x-5(3x+21)=-35
x-15x-105=-35
-14x-105=-35
-14x-105+105=-35+105
-14x=70
x=-5
y-3(-5)=21
y+15=21
y+15-15=21-15
y= 6
Answer:
x=5
y=6
Step-by-step explanation:
That is the answer

Sonia estimates that about 1 out of every 10 people is left-handed at her school. I f there are 160 students in her school, what is a reasonable number of left-handed students at Sonia's school?
Answer:
16
Step-by-step explanation:
So turn it into a percent, 1/10 is .1 or 10% so .1 x 160 = 16
Or you can divide 160/10 = 16, either way, there would be 16 left-handed students out of 160.

Help ASAP plz on this math assignment
Answer:. 38 and 52
It is given here that
angle FKY = 90.
we know angle. FKG + GKY. = FKY
so,. (7c + 24) + (5c + 42) = 90
12c + 66 = 90
12c = 90 - 66
12c = 24
c= 24/12
c = 2
then angle is
7*2+24 = 38
5*2 + 42 = 52

A master baker can decorate a cake in 6 minutes and a student baker can decorate the same cake in 12 minutes. If they work together on one cake for one min what part of the cake is left to decorate
Answer:
3/4
Step-by-step explanation:
so if it takes the master baker 6 minutes and they work on the cake for one minute that is 1/6 if it takes the student 12 minutes that is 1/12. so you do
1/12 x 1/6 and you find the LCD so that is 1x2/6x2 which makes 2/12 + 1/12 = 3/12 and you simplify by dividing the top and bottom by 3 which is 1/4 so if they decorated 1/4 of the cake that leaves 3/4 of the cake left.

Answer:
x=16[tex]\sqrt{\\2\\}[/tex]
y= 16
Step-by-step explanation:
Since we know that this is a right triangle, all sides must add up to 180°. This means that our unknown angle is 45°. With two 45° angles, we know that side y must be 16 (the same as the other corresponding angle). Once we know both legs, we can use Pythagorean Theorem to determine that the hypotenuse, or side x is =16[tex]\sqrt{2}[/tex]

Answer:
0, -2/70, 20, 1/30, -3Step-by-step explanation:
Factoring out the greatest common factor in each case, we can simplify the process of finding the non-zero solution. The solutions are the values of the variable that make the factors be zero.
1) 7x^2 +2x = 0 = (x)(7x +2) ⇒ x = 0; x = -2/7
__
2) 5b^2 -10b = 0 = (5b)(b -2) ⇒ b = 0; b = 2
__
3) 3d^2 -d = 0 = d(3d -1) ⇒ d = 0; d = 1/3
__
4) 17x^2 +51x = 0 = 17x(x +3) ⇒ x = 0; x = -3
