Hey there!
This equation has infinite solutions.
To solve for this equation, first add -7 to both sides in order to get rid of the constant:
2x-2x-7=-7
2x-2x=0
Now, combine your like terms or add 2x and -2x together:
2x-2x=0
0=0
Because you result in a true mathematical statement (0 is equal to itself), you have an infinite amount of solutions or all real solutions.
To check if this is true, plug in any number in place of x in the original staeltement to see if you result in a true statement:
Let's say x is 5
2(5)-2(5)-7=-7
10-10-7=-7
-7=-7
This proves that you have infinite solutions for your equation. :)
Answer:
x = (3a + 8)/b
Step-by-step explanation:
a(5 - 2) = bx – 8
bx = a(5 - 2) + 8
x = (3a + 8)/b
Answer:
12.8
Step-by-step explanation:
Here multiplication is done before addition.
Given
4.8 × 2 + 3.2 ← perform multiplication
= 9.6 + 3.2 ← perform addition
= 12.8
Answer: Danny's supermarket
Step-by-step explanation:
Danny's price- 0.75x1.5= $1.12 for 1 liter water bottle
Marta's price- $1.50 for 1.25 liter water bottle
1.12x1.25=1.40, if Danny was selling a 25% bigger bottle(making the bottle size equal to Marta's) it would cost $1.40, the lower price
Answer:
:)
Step-by-step explanation:
I think the answer is 300 or over 300. Maybe even 750, I'm not really sure
