Answer:
45/8 or 5 5/8
Step-by-step explanation:
2 1/4. 2 times 4 is 8 plus 1 is 9 (9 over 4 (9/4)). 2 1/2. 2 times 2 is 4 plus one is 5. (5 over 8 (5/2)). 9/4 x 5/2. 9 times 5 is 45, 4 times 2 is 8. you get the improper fraction 45/8. 45 simplified is 5 5/8. hope i helped.
Answer:
45/8 or 5 5/8
Step-by-step explanation:
When multiplying fractions, it ALWAYS so much easier to make them into improper fractions (for me at least). When doing this, multiply the denominator to the whole number and add the numerator and keep the denominator the same. So, for 2 1/4, you could use the equation 2(4) + 1 = x/4. You should get 9/4. Doing this for the other mixed fraction, you get 5/2.
Multiplying fractions is pretty straightforward after that. You don't have to change the denominators to match each other like you do when adding, instead you just multiply straight across. Multiply both of the numerators and then the denominators.
Numerators: 9 x 5 = 45
Denominators: 4 x 2 = 8
So, you get 45/8. If you're wanting a mixed number fraction, just divide 45 by 8. 8 goes into 40 5 times, and you get a left over number 5. Therefore, as a mixed fraction you get 5 5/8.
I don't know how you wanted me to show my work, but I tried the best I could to explain.

what is the y intercept of 2y - 2x = 8
Answer:
Step-by-step explanation:
Write in y = mx + b form
here, b ----> y intercept
2y - 2x = 8
2y = 2x + 8 {Divide the equation by 2}
[tex]\frac{2y}{2}=\frac{2x}{2}+\frac{8}{2}\\[/tex]
y = x + 4
y-intercept = 4

Answer:
lower left
Step-by-step explanation:
We notice that the answer choices have only the first equation changed. The equivalent of the first equation must have the same ratios of coefficients.
x-coefficient : y-coefficient : constant
= 2 : 1 : -15 . . . . . in the given equation
2 : -2 : 30 = 1 : -1 : 15 . . . upper left — not the same
-4 : -2 : -15 = 4 : 2 : 15 . . . upper right — not the same
-4 : -2 : 30 = 2 : 1 : -15 . . . lower left — same as the given equation
-4 : 1 : 30 = 4 : -1 : -30 . . . lower right — not the same

In ΔUVW, the measure of ∠W=90°, the measure of ∠U=19°, and WU = 85 feet. Find the length of VW to the nearest tenth of a foot.
Answer:
29.3feet
Step-by-step explanation:
In ΔUVW, the measure of ∠W=90°, the measure of ∠U=19°, and WU = 85 feet. Find the length of VW to the nearest tenth of a foot.
From the triangle given
<W = 90 degrees
<U = 19 degrees
<V = 180 - (90+19)
<V = 180 - 109
<V = 71 degrees
Using SOH CAH TOA
tan theta = opp/adj
tan <V = WU/VW
tan 71 = 85/VW
VW = 85/tan 71
VW = 85/2.9042
VW = 29.27
Hence the length of VW to the tenth of a foot is 29.3feet
29.3 is in fact the correct answer

y=6x-14 & y=-2x+34 solved in the substitution method
Answer:
x = 6.125
Step-by-step explanation:
y = -2 + 34
so
-2x + 34 = 6x - 15
+2x +2x
34 = 8x - 15
+15 +15
49 = 8x
x = 6.125
