All of the following expressions simplify to -5x + 7, except ( x - 2) - (6 x - 9) (5 x + 1) - (-10 x + 6) -4 x + 2 x + 7 - 3 x (4 x + 3) + (-9 x + 4)
Answer:
(-4x+2)+(7-3x)
Step-by-step explanation:
it would give you -7x+9 I believe the others all equal -5x+7

Answer:
x = 5
Step-by-step explanation:
4x + 2y + z = 24
2x - 3y - z = 2
5x + y + 2z = 21
-----------------
Eliminate z
Add the 1st and 2nd eqn
4x + 2y + z = 24
2x - 3y - z = 2
----------------
6x - 1y = 26 eqn A
Multiply the 2nd eqn by 2, then add the 3rd.
4x - 6y -2z = 4
5x + y + 2z = 21
----------------
9x - 5y = 25 eqn B
---------------
Now you have 2 eqns in 2 unknowns, not 3.
Multiply eqn A by 5 and subtract eqn B.
30x - 5y = 130 eqn A times 5
9x - 5y = 25 eqn B
-------------
21x = 105
x = 5
Answer:
x = 5 is the answer

Answer:
8: 73.2 cm
10: 738 mm
Step-by-step explanation:
8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm
10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm
Answer:
8: 73.2
10: 738
Step-by-step explanation:
Area of a trapezoid = [tex]A=\frac{a+b}{2} h[/tex]
where a and b = base lengths and h = height
For #8
These are the given dimensions
Base 1 = 4.5
Base 2 = 7.5
Height = 12.2
All we have to do is plug in the values into the formula
So....
[tex]A=\frac{4.5+7.5}{2} 12.2\\4.5+7.5=12\\\frac{12}{2} =6\\6*12.2=73.2[/tex]
Hence the answer is 73.2cm²
For #10
Once again all we have to do is plug in the values into the formula
[tex]A=\frac{22+19}{2} 36\\22+19=41\\\frac{41}{2} =20.5\\20.5*36=738[/tex]
Hence the answer is 738

If 30% of a number equals 8, find 90% of that number.
Answer:
8.88
Step-by-step explanation:
I believe it is 8.88 becuase this question is asking to find 90% pf that number.
What do you need to do?
you have to make a proportion.
8/x 90/ 100
You would now cross multiply. 90* x = 90x 8*100= 800
the equation you would need is 90x = 800. divide them and you get 8.88.
ROUNDED: you get 9.
I believe this is correct sorry if it was incorrect.

Answer: 7/10, 7/10 and 3/10.
Step-by-step explanation:
7/10 = Between 1 and 10, the multiples of three are 3, 6, and 9. So the amount favourable outcomes is the total minus the multiples, 10-3 = 7. So 7/10.
7/10 = Between 1 and 10, the multiples of 2 are 2, 4, 6, 8, and 10. The multiples of 3 are 3, 6 and 9. That, gives 7 favourable outcomes (6 is a multiple of both but counted once) giving the probability of 7/10.
3/10 = The favourable outcome is 8 and above, so: 8, 9 and 10. There are 3 favourable outcomes which gives the probability of 3/10.

The volume of a right rectangular prism is 70 7/8 cubic feet and its base is a square with a side length of 4 1/2 feet. what is the height?
Answer:
7/2 feet
Step-by-step explanation:
Volume of Right Rectangular Prism: V = w * h * l
You are given the volume, and the base (which would include l and w)- and are told to find h.
70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)
70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)
7/2 feet = h
The height will be 7/2

John has a box of nails. The box contains 65 small nails, 40 medium nails, and 45 large nails. Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box. There are 176 medium nails in Susan's box.
What is the total number of nails in Susan's box?
Answer:
326
Step-by-step explanation:
Add a nails: 65+40+45+176= The answer
660
Step-by-step explanation:
John
65s (small)
40m (medium)
45 L (large)
Susan
x small
176m
y large
From question:
Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box =Meaning same ratio
John ratio. Susan
s : m : L s : m : L
65 : 40 : 45. 13 : 8 : 9
13 : 8 : 9. x : 176 : y
x = (176/8)*13
=286
y = (176/8) * 9
= 198
Total number of nails in Susan box
= x + 176 + y
= 286 + 176 + 198
=660

Jasraj left his house and walked 1500 m east to the supermarket. He then walked another 500 m east to the comic store before walking back home the same way he came. How many kilometers did Jasraj walk altogether?
Answer:
Jasraj walked 4 kilometers all together
Step-by-step explanation:
First, add.
1,500 + 500 = 2,000
Then, multiply by 2.
2,000 × 2 = 4,000
Now, we have to convert to kilometers.
1 kilometer = 1000 meters
4,000 ÷ 1,000 = 4
So, Jasraj walked 4 kilometers!
Have a wondeful day! :)
