Need those done by 33 minutes you have to use system of equations substitution thank you
Answer:
1. y=4
y=x+7
4=x+7
x= -3 , y= 4
2. y=3x
y=x+5
3x=x+5
2x=5
x=5/2 or 2.5
y= 3(5/2)
y= 15/2 or 7.5
x= 2.5, 7= 7.5
Answer:
1. x= -3 2. x= 5/2
Step-by-step explanation:
You need to substitute the second y equation given into the first one to find x. Then get x by itself on one side.
1. 4= x + 7
-7 -7
-3 = x
x= -3
2. 3x= x + 5
-x -x
2x= 5
(2x= 5) /2
x= 5/2

The weight of 100 earth worms is recorded in a grouped frequency table. The
cumulative frequency is calculated and displayed in the table below.
What is the value of q?
Answer:
q = 80
Step-by-step explanation:
Here, we want to get the value of w
Mathematically, we can obtain the cumulative frequency from the frequency tab
To do this, we have to sum up the frequencies at each point to get the cumulative at each point
We add the frequency above to the frequency below to get the value of the cumulative frequency at that point
We have it that;
we start with 10: as seen on the frequency column
then we proceed;
10 + 20 = 30
30 + 30 = 60
60 + 20 = 80
80 + 10 = 90
90 + 10 = 100
As we can see here, the value of q is 80
What is the area of this regular hexagon that has been divided into six congruent triangles?
336 cm2
242 cm2
168 cm2
84 cm2
The area of this hexagon that has been divided into six congruent triangles will be 168 cm².
What is a hexagon?A closed two-dimensional polygon with six sides is what is known as a hexagon in geometry.
Types of Hexagons
1. Regular Hexagon ⇒ It is a regular hexagon when the lengths of all the sides and the measures of all the angles are equal.
2. Irregular Hexagon ⇒ The length of the sides and the measure of the angles are not equal in an irregular hexagon.
Given that hexagon with a side of 7cm and the height of each triangle is 8cm.
Area of one triangle = (1/2)× base × height
⇒ (1/2) × 7 × 8
⇒ 28 cm²
Now the area of the complete hexagon is 28 × 6 = 168 cm² hence, the area of the given hexagon will be 168 cm².

What do I do plz help
Answer:
x = 54°
Step-by-step explanation:
90° = 2x-18°
90° + 18° = 2x
108° = 2x
x = 54°
Answer:
x = 54
Step-by-step explanation:
The two angles added together equal 90 degrees because they are complementary angles.
x - 18 + x = 90
Combine like terms
2x - 18 = 90
add 18 to both sides
2x = 108
Divide each side by 2
x = 54
Fill in for x
54 - 18 + 54 = 90
36 + 54 = 90
90 = 90
This proves that the answer is true.

Given are the graphs of the functions f(x)=√x and g(x)=2 sinx. Use the graph or graph the functions on your own and determine all values of x that solve the equation f(x)=g(x). Explain how you identified the solutions.
The values of [tex]x[/tex] that solve the equation [tex]f(x) = g(x)[/tex] are 0, 0.256 and 2.285, respectively.
How to solve graphically two equations by graphic approach
In this question we must look for all points where each curve intersects each other. By direct inspection on figure given, we conclude that [tex]f(x) = g(x)[/tex] happens in thrice: (i) [tex](x,y) = (0, 0)[/tex], (ii) [tex](x,y) = (0.256, 0.505)[/tex], (iii) [tex](x,y) = (2.285, 1.512)[/tex]
Hence, the values of [tex]x[/tex] that solve the equation [tex]f(x) = g(x)[/tex] are 0, 0.256 and 2.285, respectively.

Find sin J, cos J, and tan J as
a fraction in simplest form.
Find the missing side.
Round to the nearest tenth.
Answer:
sin J = [tex]\frac{15}{29}[/tex]
cos J = [tex]\frac{21}{29}[/tex]
tan J = [tex]\frac{5}{7}[/tex]
x = 14.6
Step-by-step explanation:
1st pic:
1st, find the missing side lenght:
[tex]a^{2} = c^{2} - b^{2}[/tex]
[tex]a^{2} = 58^{2} - 42^{2}[/tex]
[tex]a^{2} = 3364 - 1764[/tex]
[tex]\sqrt{a^{2}} = \sqrt{1600}[/tex]
a = 40
sin = [tex]\frac{opposite}{hypothenuse}[/tex] ⇒ [tex]sin J = \frac{30}{58} = \frac{15}{29}[/tex]
cos = [tex]\frac{adjacent}{hypothenuse}[/tex] ⇒ [tex]cosJ = \frac{42}{58} = \frac{21}{29}[/tex]
tan = [tex]\frac{opposite}{adjacent}[/tex] ⇒[tex]tanJ = \frac{30}{42} = \frac{5}{7}[/tex]
2nd pic:
use sine:
sin = [tex]\frac{opposite}{hypothenuse}[/tex]
sine 59 = [tex]\frac{x}{17}[/tex]
sine of 59 is 0.857:
0.857 = [tex]\frac{x}{17}[/tex]
multiply 17 on both sides:
0.857 x 17 = [tex]\frac{x}{17}[/tex] x 17
14.569 = x

There are 100 coins with a total value of $10.15. How many quarters do you have? How many dimes do you have?
9514 1404 393
Answer:
99 dimes1 quarterStep-by-step explanation:
If all 100 coins were dimes, the value would be $10.00. Each dime traded for a quarter adds $0.15 to the value.
The actual value of the coins is $10.15 -10.00 = $0.15 more than it would be for all dimes. This indicates 1 dime has been traded for a quarter.
There are 99 times and 1 quarter.

A function C(x) = 8x + 15 represents the cost C. in dollars of producing x, T-shirts for
the marching band.
what would be the cost of producing 60 t shirts?
find the number of t shirts if c(x)=303
Answer:
The cost of producing 60 t-shirts is $495.
36 t-shirts will let the cost, C(x) = 303
Step-by-step explanation:
If we producing 60 t-shirts, then we plug in 60 for the x, which x represents t-shirts for the marching band.
C(x) = 8x + 15
C(x) = 8(60) + 15
C(x) = 480 + 15
C(x) = 495
If the cost of the t-shirts is 303, we plug in 303 for the cost,C(x).
C(x) = 8x + 15
303 = 8x + 15
288 = 8x
x = 36
