Answer:
Mile = length
Cup = Volume
Pound= Mass
Centimeter = length
Liter = volume
Gram = mass
pint = volume
yard=length
kilogram=mass
teaspoon=volume
millimeter=length
Step-by-step explanation:
Given that a coupon for $15 off will be applied on purchases over $100, the given discounted price of the jacket is $203. Since this is the discounted price, then it should be the price after the coupon has been used. To find the retail (or original) price, we simply add 15 back to 203. So the retail price should be $218.
To make a square for x²+bx=c, add(
)²on both side
in this case, b is-3/4, half of b is -3/8, and (-3/8)² is 9/64, so you add 9/64 to both side.
Answer:
Step-by-step explanation:
1. x+2y=6 or x=6-2y
3x-2y=2
3(6-2y)-2y=2
18-6y-2y=2
18-8y=2
-8y=-18+2
-8y=-16
y=-16/-8
y=2 ans.
x+2*2=6
x+4=6
x=6-4=2 ans.
Proof:
3*2-2*2=2
6-4=2
2=2
I leave the rest for you to practice with.
3. 4x+y=7
2x+5y=-1
5. 3x+2y=-2
6x-y=6
Solve the system using the elimination method. Show all your steps.
7. -3x+3y=3
3x+y=9 add.
---------------------------------
4y=12
y=12/4
y=3 ans.
3x+3=9
3x=9-3
3x=6
x=6/3
x=2 ans.
Proof:
-3*2+3*3=3
-6+9=3
3=3
I'll leave the rest for practice.
9. -5x+12y=20
x-2y=-6
11. 3x+2y=1
4x+ 6y= 7
Answer:
Inequaliy: 2x-3(12)>60
X>48
Step-by-step explanation:
Since area of a rectangle is W(L)=A
The inequality given right here including length And width and area Plugged in would be
2x-3(12)>60. (It’s >60 because the area stated in the problem said to be greater then 60 so we put a Greater then sign)
Combine like terms and solve
2x-36>60
Add 36 on both sides
2x>96
Divide 2 on both sides to isolate variable
x>48
Check:
2(50)-36>60 ( I used 50 because it’s greater then 48 and it’s a easy number to work with for just a check)
solve:
100-36>60
64>60✔️
