30 POINTS IF U ANSWER!
Alonso paid for repairs on his car, and 3
5
of the bill was for labor costs. How much was the total bill if the cost of the labor was $79.50? Let b = the amount of the total bill.
Which equation and solution is correct?
Five-thirds b = 79.50, and the total bill was $47.70.
Three-fifths (79.50) = b, and the total bill was $127.20.
Five-thirds b = 79.50, and the total bill was $212.00.
Three-fifths (b) = 79.50, and the total bill was $132.50.
Answer:
132.50
Step-by-step explanation:
3/5b = 79.50
b = (79.50) / (3/5)
b = 79.50 * 5/3
b = 397.50/3
b = 132.50
132.50 is the total bill

Answer:
-10
Step-by-step explanation:
The equation would be -8 - (-10) = 2. When subtracting a negative, you are actually just adding a positive. It's like the two negative signs cancel each other out, so it would look more like -8 + 10 = 2. For the answer box, just put -10.
5x+4=5x+4 is it one solution, no solution, or infinite solutions?

Answer:
Step-by-step explanation:
∠5 = ∠1 {Alternate exterior angles are congruent}
8x - 19 = 7x - 3
Add 19 to both sides
8x = 7x - 3 + 19
8x = 7x + 16
Subtract 7x from both sides
8x - 7x = 16
x = 16
∠5 = 8x - 19
= 8*16 - 19
= 128 - 19
∠5 = 109
∠5 + ∠4 = 180 {linear pair]
109 + ∠4 = 180
∠4 = 180 - 109
∠4 = 71°
Each letter of L I T T R E L L is written on a card. The cards are placed in a basket. Find each probability if Elsa selects a card, leaves it out, and then selects another card.
7. Is this an independent or dependent event? Explain: ______________________________ _____________________________________ _____________________________________
8. What is the probability of selecting a T and then an E?
9. What is the probability of selecting a T, and then another T?
10. P(E, then I)?
Step-by-step explanation:
7. I believe it's independent because it makes sense and if it was dependent it wouldn't make senses.
8.For T you have 2 (Ts) so that give you a 2/8= 25% so you would basically make those Ts disappear and focus on 1 out of 6 and you'd get a 16.67% chance
9. 14.2857%

how to use union in the real world?
Answer:
To overcome such type of real world problems we use union. Unlike structures union occupies single memory location to store all its members. So, unions are helpful when you want to store value in single member from a set of members. Size of union is defined according to size of largest member data type.
Step-by-step explanation:
In union, all members share the same memory location. For example in the following C program, both x and y share the same location. If we change x, we can see the changes being reflected in y. #include <stdio.h> // Declaration of union is same as structures.

r25=35
r=35/25
r=1.4
substitution
r160=t*15
t=time
r=1.4

Put the following equation of a one into a slope -intercept form, simplifying all fractions.
8x+6y=-54
Answer:
y = -4/3x -9
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
8x+6y = -54
Subtract 8x from each side
8x+6y-8x = -8x-54
6y = -8x-54
Divide each side by 6
6y/6 = -8x/6 -54/6
y = -4/3x -9
Answer:
y = -4/3x - 9
Step-by-step explanation:
Putting this into 'y=mx+c' form:
i) Firstly, make it only y on the LHS:
6y = -8x-54
ii) Secondly, making the 'y' have a co-efficient of 1. This can be done by dividing both sides by 6:
6y/6 = -8x/6 - 54/6
y = -4/3x - 9
Hence,
y = -4/3x - 9

I need help with find this problem out
Answer:
Step-by-step explanation:
Hi there!
∠SRQ = 162°
∠STR = 130°
∠RST = ?
Now;
∠SRQ = ∠RST+∠STR [external angle is equal to the sum of opposite interior angles of triangle]
∠RST = ∠SRQ-∠STR
∠RST = 162°-130°
Therefore, the measure of ∠RST is 32°.

What is the slope of this line?
a. -1/3
b. 1/3
c. 2/3
d. -2/3
Answer:
c. 2/3
Step-by-step explanation:
Since the line is going up to the right it is a positive slope. Therefore it can't be a or d.
The slope is 2/3 because to connect the dots you have to go up 2 and to the right 3.
