Solve the system by substitution.
4x + 7y = -41
x = y + 5
Answer:
x=-6/11, y=-61/11. (-6/11, -61/11).
Step-by-step explanation:
4x+7y=-41
x=y+5
-----------------
4(y+5)+7y=-41
4y+20+7y=-41
11y=-41-20
11y=-61
y=-61/11
x=-61/11+5=-61/11+55/11=-6/11
Apply the distributive property and simplify. -9(x+2)=45 -9x+(__)=45
An African elephant weighs 2 tons. How many pounds are in a herd with 26 elephants? Note: 1 ton = 2,000 pounds
Answer:
the answer is 104,000
Step-by-step explanation:
because if an elephant is two tons and 1 ton is 2000 lbs then you know that each elephant is 4000 lbs so then you have to multiply 4000 by 26 wich gives you 104,000
Step-by-step explanation:
2tons multiplied by 1 elephant will give is=4000
26*4000=104000
a herd of elephant weighs 52000 pounds

What is the number? I did many ways but i didn't found it, please guys help me with it.
Answer:
A). 15
B). -1.2
Step-by-step explanation:
A). [10(x+3)]-20 = 160
10x+30-20 = 160
10x+10 = 160
10x = 160-10
10x = 150
x = 150/10
x = 15
B). 5{[4(8+(5x))]-9} = 85
5(32+20x+9) = 85
5(32+9+20x) = 85
5(41+20x) = 85
205+100x = 85
100x = 85-205
100x = -120
100x/100 = -120/100
x = -1.2

the school store has1200 pendls in stock and sells and sells an average of 25 pencils per day the manager reorders when the number of pencils in stock in 650
Answer:
Number of pencils in stock = 1200
Average number of pencils sold by the manager per day = 24
Number of pencils that would be sold before reordering = 1200 - 500
= 700
Then
The number of days after which the manager will reorder = 700/24
= 29.16
So the manager has to reorder after about 30 days. Since the answer comes in fraction of more than 29 days, so it has to be 30 days. I hope the procedure is clear for your understanding.
Just to be clear, this answer is not mine, but I remember seeing this question so I just copied someones' answer. Still, you might find this helpful.

5x-(2x-13)=40
Answer:
9
Step-by-step explanation:
open the bracket, you will have
5x-2x+13=40
collect like terms
5x-2x=40-13
3x=27
divide both side by 3
3x/3=27/3
x=9
Answer: 9
Step-by-step explanation:
5x-(2x-13)=40
Open bracket by -1
5x-2x+13. = 40
3x. = 40-13
3x. =. 27
Divide both sides by 3

9. The functions f and g are such that
f(x) = 3(x – 4) and g(x) = x/5+1
a) Find the value of f(10)
b) Find g-'(x)
c) Show that ff(x) = 9x - 48
Answer:
a) f(10) = 18
b) g-¹(x) = 5x-5
c) 3((3(x-4))
= 3((3x-12)-4))
= 3(3x-16)
= 9x-48
The value of f(10) = 18, g'(x) = 1/5 and ff(x) = 9x - 48
What is function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
Given that, The functions f and g are such that f(x) = 3(x – 4) and
g(x) = x/5+1
a) f(10) = 3(10-4)
= 3(6)
= 18
b) g'(x) = d/dx(x/5+1)
= 1/5d/dx(x) = 1/5
c) ff(x) =
= 3((3(x-4))
= 3((3x-12)-4))
= 3(3x-16)
= 9x-48
Hence, The value of f(10) = 18, g'(x) = 1/5 and ff(x) = 9x - 48

Which expression can you substitute in the indicated equation to solve the system below 5x+y =8 x+4y=2
Answer:
x = 1.58 and y = 0.105
Step-by-step explanation:
Given equations are :
5x+y =8 ...(1)
x+4y=2 ...(2)
Multiply equation (2) by 5.
5x+20y=10 ..(3)
Subtract equation (1) from (3).
5x+20y-(5x+y) = 10-8
5x+20y-5x-y = 2
19y = 2
y = 0.105
Put the value of y in equation (2).
x+4(0.105)=2
x = 2-0.42
x = 1.58
Hence, the values of x and y are 1.58 and 0.105.
