Answer:
Step-by-step explanation:
<u>Given:</u>
- Quarter = 25 ¢, number of quarters = q
- Dime = 10 ¢, number of dimes = d
- Total amount = $13.20 = 1320 ¢
<u>Required equations:</u>
- q + d = 72
- 25q + 10d = 1320
<u>Solve by elimination, multiply the first equation by 10 and subtract from the second equation:</u>
- 25q + 10d - 10q - 10d = 1320 - 10*72
- 15q = 600
- q = 600/15
- q = 40
<u>Find p:</u>
- 40 + p = 72
- p = 72 - 40
- p = 32
Answer:
6^-1
Step-by-step explanation:
6^-6 - (-5) = 6^(-6 + 5) = 6^(-1)
A lot of things are going on in this question. Notice how the 5 is handled. It starts off in the denominator as - 5 and when brought to the numerator it becomes -(-5) which makes it + 5.
The answer is then easy. It is 6^(-6 + 5) = 6^-1
You could give the answer as 1/6 but that is not what the question says.
Answer:
(C)x=11.6, y=23.2
Step-by-step explanation:
Using Theorem of Intersecting Secant and Tangent
Applying this theorem in the diagram, we have:
Next, we apply Theorem of Intersecting Chords
PV X VQ=SV X VR
4 X x= 2 X y
Recall earlier we got: x=11.6
2y=4 X 11.6
2y=46.4
Divide both sides by 2
y=46.4/2=23.2
Therefore: x=11.6, y=23.2
Answer:
C is the answer
Step-by-step explanation:
If you multiply 58 to 6 gives you 348
Hope this helps
Answer:
x = 5
Step-by-step explanation:
(since the equations are equal to eachother, add similiar factors)
4x - 3 = 2x + 7
+3. -2x
2x = 10
<em>Simplify</em>
x = 5
