Answer:
7. (2,1) 8. (8,2)
Step-by-step explanation:
Step: Substitute4z−7foryin5y+3z=11:
5y+3z=11
5(4z−7)+3z=11
23z−35=11(Simplify both sides of the equation)
23z−35+35=11+35(Add 35 to both sides)
23z=46 Divide both sides by 23
x=2
Substitute2forxiny=4z−7:
y=4z−7
y=(4)(2)−7
y=1
Step: Solve2x+4y=24for x:
2x+4y+−4y=24+−4y(Add -4y to both sides)
2x=−4y+24
x=−2y+12
−2y+12forxin−2x+8y=0:
−2x+8y=0
−2(−2y+12)+8y=0
12y−24=0(Simplify both sides of the equation)
12y−24+24=0+24(Add 24 to both sides)
12y=24 Divide both sides by 12
y=2
Substitute2foryinx=−2y+12:
x=−2y+12
x=(−2)(2)+12
x=8
Slove by using elimination
3x+7y=27
-3x+y=21
Answer:
x = -5
y = 6
Step-by-step explanation:
3x + 7y = 27 --------------(I)
-3x + y = 21 -----------(II)
Add equation (I) & (II) and so x will be eliminated and we can find the value of y.
(I) 3x + 7y = 27
(II) -3x + y = 21 {add}
8y = 48
y = 48/8
y = 6
Plugin y = 6 in equation (I)
3x +7*6 = 27
3x + 42 = 27
3x = 27 - 42
3x = -15
x = -15/3
x = -5

The base of a right triangle is 2 meters greater than the height. If the area of the triangle is 100 m2, what are the dimensions of the base and the height?
Answer:
b = 15.2 m
h = 13.2 m
Step-by-step explanation:
The area of a right triangle is given by:
[tex] A = \frac{bh}{2} [/tex] (1)
Where:
b: is the base
h: is the height
If the base is 2 meters greater than the height we have:
[tex]b = h + 2[/tex] (2)
And if the area of the triangle is 100 m², the dimensions of the base can be found by entering equation (2) into (1):
[tex]100 m^{2} = \frac{(h + 2)*h}{2}[/tex]
[tex] 200 m^{2} = h^{2} + 2h [/tex]
[tex] h^{2} + 2h - 200 m^{2} = 0 [/tex]
By solving the above quadratic equation we have:
[tex] h = 13.2 m [/tex]
And by entering the above value into equation (2) we have:
[tex]b = 13.2 + 2 m = 15.2 m[/tex]
Therefore, the dimensions of the base and the height are 15.2 m and 13.2 m respectively.
I hope it helps you!

The weight of 20 buckets is 141 Kg.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
weight of 1 bucket of gravel = 7.05
weight of 20 buckets = 7.05 x 20
= 141 Kg
Hence, the weight of 20 buckets is 141 Kg.

Step-by-step explanation:
x and y go up at a constant rate (or you can say it has a CROC or constant rate of chacge) y going up 5 for every one x
with our equation being y = 5x + 5
hope this helps <3
Answer:
Step-by-step explanation:
It would be D because to know if its linear, x has to increase by 1 and y by a constant rate.

-4.8 (6.3x-4.18)=-58.56 what is x?
Answer:
x = 2.825
Step-by-step explanation:
-4.3(6.3x + -4.18) = -58.56
-4.3(-4.18 + 6.3x) = -58.56
(-4.18 * -4.3 + 6.3x * -4.3) = -58.56
(17.974 + -27.09x) = -58.56
17.974 + -27.09x = -58.56
17.974 + -17.974 + -27.09x = -58.56 + -17.974
0.000 + -27.09x = -58.56 + -17.974
-27.09x = -58.56 + -17.974
-27.09x = -76.534
x = 2.825175341
