These questions can be daunting at first, but they're pretty simple to solve.
First, we need to establish a common denominator. We have 2 / 3, 1 / 4, and
-4 / 3. The least common denominator we can get is by multiplying 4 and 3 together to get 12. So we will change the denominator as follows;
2 / 3, 1 / 4, -4 / 3 = 8 / 12, 3 / 12, -16 / 12
Now we can put these back into the equation.
8/12x + 3/12 = -16/12
8x + 3 = -16
It's simple math from here on out, but I'll show the process. What we can basically do now is take away the denominator because it doesn't matter now that it's common.
Subtract 3 from both sides. Now we have 8x = -19
Dividing by 8 on both sides of the equation will get you your answer.
x = -19/8
Hope this helps!
5x - 2 > 7
x = 2, 3, 4, 5.
for x = 2, 5*2 - 2 = 8 > 7
for x = 3, 5*3 - 2 = 13 > 7
for x = 4, 5*4 - 2 = 18 > 7
Answer:
$8
Step-by-step explanation:
We can write an equation with the scenario given and solve for what we need, Alberto's weekly allowance.
Let his weekly allowance be "x"
Since he spend HALF of it, he spent 0.5x of it.
He has remaining also 0.5x of it
Now, whatever he has (0.5x), he gets $4 more from cleaning windows. After that he has:
0.5x + 4
This amount is equal to $8, so we can write:
0.5x + 4 = 8
0.5x = 8 - 4
0.5x = 4
x = 8
So, alberto's weekly allowance is $8
Answer:
41.82$
Step-by-step explanation:
The prices are
7.58$, 16$, 18.24$.
To get the total of all what Lucy bought, You add the prices altogether.
That is,
18.24$
+16.00$
+<u>0</u><u>7</u><u>.</u><u>5</u><u>8</u><u>$</u>
41.82$
The total amount of what Lucy bought is 41.82$
