Answer:
Step-by-step explanation:
Equation:
Jalil says it is not possible to isolate x because x has a different unknown coefficient.
Victoria t. Victoria believes there is a solution
Solving the equation:
So, this shows x can be isolated .
Victoria was right .
It was not possible to isolate x if the coefficients of x would be same .
But in the given equation the coefficients of x are not same .
So, Victoria is right.
Answer:
A. Rewrite the expression on the left using the distributive property.
Step-by-step explanation:
a. 52 to 2
b. 11 to 286
c. 26 to 1
d. 5 to 130
e. 0.25 to 6.5
f. 1/2 to 19 1/2.
The required Rob has 16 dimes and 24 quarters as he has a total of 40 coins.
The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let x be the number of dimes that Rob has, and y be the number of quarters.
We know that he has a total of 40 coins, so,
x + y = 40 ( 1)
We also know that the value of all his coins is $7.60. The value of x dimes is 10x cents, and the value of y quarters is 25y cents. So,
10x + 25y = 760 ( 2)
Now we can solve for x and y. Let's start by solving equation 1 for one of the variables:
x + y = 40
y = 40 - x
Substitute this expression for y into equation 2:
10x + 25y = 760
10x + 25(40-x) = 760
10x + 1000 - 25x = 760
-15x = -240
x = 16
So Rob has 16 dimes. We can use equation 1 to find the number of quarters:
x + y = 40
16 + y = 40
y = 24
So Rob has 24 quarters.
Therefore, Rob has 16 dimes and 24 quarters.

Answer:
The baker baked 375 loaves of bread that day.
Step-by-step explanation:
Let the baker baked a total of x loaves of bread.
240 loaves were sold by the end of the day.
The baker was then left with 9/25 of the number of loaves that were baked.
We get the equation:
Solving for x;
=>
=>
=>
=>
x = 375
Therefore, the baker baked 375 loaves of bread that day.
