Solve the system of linear equations by using the elimination method:
4x+ y = 36
8x- y = 60
Answer:
(8,4)
Step-by-step explanation:
y and -y cancels out leaving you with "12x=96"
that simplifies to "x=8"
Then you substitute 8 into the "x" from either equation and y should equal 4
The rainfall amount last year was 6 inches below normal. The rainfall this year was 13 inches more than last year. What is the difference between the rainfall amount this year and the normal amount of rainfall? (Hint: Draw a number line to help you visualize the scenario)
Answer:
7
Step-by-step explanation:
The term difference means to subtract. Therefore, 13in - 6in, is equal to 7 inches.
13-6=7

Answer:
CD=10.15m
Step-by-step explanation:
Find the distance of BC.
Tan(40)=55/BC
BC=65.55m
Find the distance of BD.
Tan(36)=55/BD
BD=75.70m
Use BC and BD to find CD
BD-BC=CD
75.70-65.55=CD
CD=10.15m

Answer: 8y^6x^6
Step-by-step explanation:
Volume = l*w*h so multiply all the variable by multiplying the numbers and adding the exponents so
2y^2*4x^4y=8y^3x^4
then 8y^3x^4*x^2y^3=8y^6x^6

find wx? please help
Answer:
wx = 116 /11
= 10.54
Step-by-step explanation:
plz follow me
Answer: 29
see in the picture, WX is the median of the trapezoid
=> WX = (ST + UV)/2
⇔ 7x + 8 = (10x + 5 + 8x - 1)/2
⇔ 7x + 8 = (18x + 4)/2
⇔ 7x + 8 = 9x + 2
⇔ 2x = 6
⇔ x = 3
with x = 3 => WX = 7.3 + 8 = 21 + 8 = 29

Given:
Figure of a parallelogram.
To find:
The values of x and y.
Solution:
If two parallel lines intersected by a transversal line, then the alternate interior angles are congruent.
[tex]4x=24[/tex] (Alternate interior angles)
[tex]x=\dfrac{24}{4}[/tex]
[tex]x=6[/tex]
And,
[tex]y-10=32[/tex] (Alternate interior angles)

Step-by-step explanation:
All of the angles add up to 180 so to solve for X you do (x) + (2x-5) + (62) = 180. Solve for X and you get 41. Lastly plut the answer back into the equation.
Check all the true statements.
Answer:
The true statements are:
2DE = AC1/2AC = DEDE || ACStep-by-step explanation:
As we are given,
AD = 3.5 and BD = 3.5
CE = 3 and BE = 3
From the given triangle ΔABC, it is clear that:
The segment DE bisects the sides AB and BC, so
AD = BD
CE = BE
It is clear that the segment DE is parallel to the segment AC, thus
DE || AC
As DE is the midsegment between AB and BC, so
2DE = AC
1/2AC = DE
Thus, the true statements are:
2DE = AC1/2AC = DEDE || ACEvaluate the expression below. 18 - 71- 4 + 3(-1)

What is the image point of (4,5)(4,5) after a translation left 5 units and down 3 units?
Answer:
The image of point (-1,2)
Step-by-step explanation:
Step(i):-
Given point ( 4,5)
The Horizontal translation left '5' units then the transformed to
(x ,y ) → (x - 5 ,y)
(4,5)→ (4-5 , 5)
Step(ii):-
Again the vertical translation down '3' units then transformed to the co-ordinate point is (x, y)→ ( x, y-3)
(4-5 , 5)→ ( 4-5 , 5 -3)
(-1 , 5) → (-1 , 2)
Final answer:-
The image of point (-1,2)

Your next Pre-Algebra test is worth 93 points and contains 38 multiple choice and short answer problems. Each
multiple choice problem is worth two points and each short answer is worth three points. How many of each type of
problem is on the test?
Answer:
There are 21 multiple-choice problems and 17 short answers.
Step-by-step explanation:
Let there are x multiple-choice problems and y short answers.
ATQ,
x+y = 38 ....(1)
Each a multiple-choice problem is worth two points and each short answer is worth three points.
2x+3y = 93 ....(2)
Multiply equation (1) by 2.
2x+2y = 76 ....(3)
Subtract equation (2) and (3) we get :
2x+3y-(2x+2y) = 93-76
2x+3y-2x-2y = 17
y=17
Put the value of y in equation (1).
x+17 = 38
x=21
Hence, there are 21 multiple-choice problems and 17 short answers

Two important ingredients for baking bread are yeast and flour. To make a loaf of bread of at most 30 servings, maintain a yeast to flour ratio of 1:200. If you're making a loaf of more than 30 servings, use a ratio of 1:180. If you're making 30 servings of bread and using 0.45 oz of yeast, how many ounces of flour do you need? If you're making 90 servings of bread and using 720 oz of flour, how many ounces of yeast do you need?
If you're making 30 servings of bread and using 0.45 oz of yeast, how many ounces of flour do you need? ANSWER=90
If you're making 90 servings of bread and using 720 oz of flour, how many ounces of yeast do you need? ANSWER=4
The flour that will be used for 30 servings is 0.90 oz, while the yeast that will be used for 90 servings is 90 oz.
Given to us
To make a loaf of bread of at most 30 servings, maintain a yeast to flour ratio of 1:200.
To make a loaf of bread of more than 30 servings, maintain a yeast to flour ratio of 1:180.
Ratio for 30 ServingsA.) If We are making 30 servings of bread and using 0.45 oz of yeast,
As it is given that for 30 servings we must maintain a yeast to flour ratio of 1:200, therefore,
[tex]\rm \dfrac{Yeast}{Flour} = \dfrac{1}{200}[/tex]
Using the ratio for 0.45 oz of yeast,
[tex]\rm \dfrac{0.45\ oz}{Flour} = \dfrac{1}{200}[/tex]
[tex]\rm {Flour} = 200 \times 0.45\ oz[/tex]
[tex]\rm {Flour} = 90\ oz[/tex]
Thus, we will use 90 oz of the flour for 0.45 oz of yeast to serve 30 people.
Ratio for 90 ServingsB.) If We are making 90 servings of bread and using 720 oz of flour,
As it is given that for more than 30 servings we must maintain a yeast to flour ratio of 1:180, therefore,
[tex]\rm \dfrac{Yeast}{Flour} = \dfrac{1}{180}[/tex]
Using the ratio for 720 oz of flour,
[tex]\rm \dfrac{Yeast}{720\ oz} = \dfrac{1}{180}[/tex]
[tex]\rm {Yeast} = \dfrac{720\ oz}{180}[/tex]
[tex]\rm {Flour} = 90\ oz[/tex]
Thus, we will use 90 oz of the flour for 0.45 oz of yeast to serve 30 people.
Hence, the flour that will be used for 30 servings is 0.90 oz, while the yeast that will be used for 90 servings is 90 oz.
