Answer: x = -1 and y = -2
Step-by-step explanation:
You are given two expressions that have a relationship. There are two ways to solve this problem, but I will be going over the easy way. I'm assuming you know how to solve for one variable such as x? Well we can put the y varaible from the first equation in terms of x, from the second equation. Ill show you what I mean:
6x + 5(7x + 5) = -16
I replaced y in the first one in terms of x, so that we can solve just for x.
6x + 35x + 25 = -16
41x +25 = -16
41x = -41
x = -1
Now simply find y by plugging the now known x value into either equation
y = 7(-1) + 5
y = -2
Answer:
x = -1
y = -2
( -1, -2 )
Step-by-step explanation:
6x + 5y = -16
They gave us what "y" is and its....
y = 7x + 5
We substitute the "y" in the equation with this "y = 7x + 5
"
6x + 5y = -16
6x + 5(7x + 5) = -16
Now we need to use the distributive property (multiply what is in the parenthesis by "5")
6x + 5 * 7x + 5 * 5 = -16
6x + 35x + 25 = -16
Combine Like Terms ( 6x and 35x)
41x + 35 = -16
Subtract 25 on both sides
41x + 35 - 25 = -16 - 25
41x = -41
Divide by 41 on both sides to isolate the variable
41x/41 = -41/41
x = -1
Now that we have what "x" is (-1) we can use that to find out what "y" is.
y = 7x + 5
Substitute the x with -1
y = 7x + 5
y = 7(-1) + 5
y = -7 + 5
y = -2
x = -1
y = -2
( x, y )
( -1, -2 )

Find the area of the shaded part of circle Y.
Answer:
201.45 cm²
Step-by-step explanation:
The whole circle has an area of π(9)² cm², or 81π cm². The shaded part represents all of the circle except for the chunk swept out by sector XZ.
Sector XZ sweeps out 75°, which represents 75/360 of the whole circle, or, simplified, 15/72. That means the shaded area must represent the other 57/72. To find the area then, we can just multiply that fraction by 81π:
[tex]81\pi\cdot\frac{57}{72}=9\pi\cdot\frac{57}{8}[/tex]
Using π ≈ 3.14 and crunching the numbers out gives us a result of approximately 201.45 cm².

HELP FAS, worth 20 points
Answer:
1. infinite solutions.
2. no solutions.
Step-by-step explanation:
a. 8x + 7 = 8x + 7
The expressions are equal to each other; therefore, the equation has infinite solutions.
b. 10t - 6 = 10t + 6
10t = 10t + 12
0 = 12
These terms do not equal each other. 0 does not equal 12; therefore, this equation has no solutions.

= 4.1/100 × 30
= 41/1000 × 30
= 123/100
= 1.23%
Answer:
1.23
Step-by-step explanation:
Hey there !!!!!
4.1% of 30
if we solve it :
Y is 4.1% of 30
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 4.1% * 30
Converting percent to decimal:
p = 4.1%/100 = 0.041
Y = 0.041 * 30
Y = 1.23
therefore:
4.1% of 30 = 1.23

Leila and Joe are two partners in a business. Leila makes $3 in profits for every $4 that Jo makes. If Jo makes $32 profit on the first item they sell, how much profit does Leila make?
Answer:

Since 32 divided by 4 equals 8, and 8 times 3 equals 24, if Jo makes $32 profit on the first item they sell, Leila will make $24 profit.

Answer:
∠ HGL = 73°
Step-by-step explanation:
KL is a midsegment of the triangle and is parallel to HG, then
∠ KLJ = ∠ HGL ( corresponding angles ), so
9x - 62 = 5x - 2 ( subtract 5x from both sides )
4x - 62 = - 2 ( add 62 to both sides )
4x = 60 ( divide both sides by 4 )
x = 15
Thus
∠ HGL = 5x - 2 = 5(15) - 2 = 75 - 2 = 73°

Saj makes Rose Pink paint and Cherry Pink paint. He mixes red paint with white paint as shown. Rose Pink red : white =1:2 Cherry Pink red : white =4:3 He makes 60 litres of Rose Pink paint. To this Rose Pink paint he adds 80 litres of red paint and 28 litres of white paint. Has he now made Cherry Pink paint? You must show your working.
Answer:
No. He had not made cherry pink paint
Step-by-step explanation:
Rose Pink red : white = 1 : 2
Cherry Pink red : white = 4 : 3
...he adds 80 litres of red paint and 28 litres of white paint.
The question basically want us to check if it follows the ratio.
To have the cherry pink, the ratio must be 4:3 however the ration of paint he mixed is;
80 : 28 which is equivalent to 20 : 7
This means he had not made cherry pink paint
Adding 80 litres of red paint and 28 litres of white paint to the 60 liters of Rose pink paint does not make Cherry pink paint
The ratios are given as:
Rose pink paint-> Red : White = 1 : 2
Cherry pink paint-> Red : White = 4 : 3
When he makes 60 liters of Rose pink paint, the proportion of white and red paints are:
[tex]Red = \frac{1}{1 + 2} \times 60[/tex]
[tex]Red = 20[/tex]
[tex]White = \frac{2}{1 + 2} \times 60[/tex]
[tex]White = 40[/tex]
He then adds 80 liters of red and 28 liters of white paints.
So, the new proportions are:
[tex]Red = 20+80[/tex]
[tex]Red = 100[/tex]
[tex]White = 40+28[/tex]
[tex]White = 68[/tex]
Express as ratio
[tex]Red : White = 100 : 68[/tex]
Simplify to the smallest term
[tex]Red : White = 25 : 17[/tex]
25:17 is not equivalent to 4:3.
Hence, he has not made Cherry pink paint
