Don’t really pay attention to the x .
<u>ANSWER:
</u>
Zach has 28 dimes and 7 quarters.
<u>SOLUTION:
</u>
Given, Zach has 4 times as many dimes as quarters
And they have a combined value of 455 cents,
We need to find how many of each coins does he have?
Let, the number of dimes be x and number of quarters be y.
Then, x = 4y → (1)
Total combined value = 455 cents
x(value of one dime) + y(value of one quarter) = 455 cents
x(10 cents) + x(25 cents) = 455 cents
10x + 25y = 455 → (2)
Now, substitute (1) in (2)
10(4y) + 25y = 455
40x + 25y = 455
65y = 455
y = 7
substitute y value in (1)
x = 4(7) = 28
Hence, zach has 28 dimes and 7 quarters.
It moves in a horizontal line. Its 'y value' does not change.
Answer:
x = 11
Step-by-step explanation:
If the segments are congruent then
3x = x + 22 ➡ 3x - x = 22
2x = 22 divide both sides by 2
x = 11
The answer is 0.3.
Take for instance, a numberline. The positive numbers are always greater than the negative numbers. Even though you have this type of question:
Which number is greater +100,000 or -100,000?
The answer would still be 100,000 because any positive number is always greater
