find the solution to the equation
a) 3y + 5 = 18
b) x/4 + 13 = 10
c) -6r +2 = 3r – 6:
d) 5x-(x + 3) = 5;
e) I - (y + 2) = -14 + 5(y + 3).
Answer:
a) 3y=18-5
3y=13
3y/3=13/3
y=13/3
Step-by-step explanation:
b)x/4 =10-13
x/4 = -3
4× x/4 = -3 ×4
x = -12
c) -6r -3r = -6-2
-9r = -8
-9r/-9 = -8/-9
r = 8/9
d)5x-x -3 =5
5x-x = 5+3
4x = 8
4x/4 = 8/4
x=2

Bob can complete his Math homework in
2.5 hours, but if he works with Joe they can finish in 1.5 hours. How long would it take Joe to finish his homework on his own?
Answer:
3.75 hours
Step-by-step explanation:
Bob completes his homework in 2.5 hours.
In 1 hour, he completes 1/2.5 of his homework.
Joe completes his homework in x hours.
In 1 hour, he completes 1/x of his homework.
Together, they complete the homework in 1.5 hours.
In 1 hour, they do 1/1.5 of the homework.
1/2.5 + 1/x = 1/1.5
Convert the decimal numbers in the numerators into fractions.
1/(5/2) + 1/x = 1/(3/2)
2/5 + 1/x = 2/3
Multiply both sides by the LCD, 15x.
6x + 15 = 10x
-4x = -15
x = 3.75
Answer: 3.75 hours
Find the indicated side length round to the nearest tenth),
Answer:
Step-by-step explanation:
for 1 they give us an angle and the side next to that angle.. or the Adjacent side and they want to know the Opposite side from the angle sooo let's use ..
SOH CAH TOA
hmm TOA seems good , it's got the adj and Opp in it ,
Tan(Ф) = Opp / Adj
Tan(67) = Opp / 26
26 * Tan(67) = Opp
61.2521 = Opp
61.3 ( rounded to nearest 10th ) does this seem big to you? well it should be quite a bit bigger than the 25 on the base, seems about right to me
for 2 they give us one angle, 48 , and one side, 35 , that is opposite from that angle, and ask what is the Hyp. So find a trig function that has those pieces in it. SOH seems good
sin(Ф) = Opp / Hyp
sin(48) = 35 / Hyp
Hyp = 35 / sin(48)
Hyp = 47.0971 ( and that seems about right for the Hypotenuse )
x = 47.1 ( rounded to the nearest 10th )
for 3 they are asking us to imagine a triangle, I'll draw it and attach it as a picture. Looking at the picture helps a lot, we can see we have the angle and the adj side and want to find the Opposite side of that big triangle. sooo use TOA , it's got those pieces in it
Tan(17) = Opp / 200
200*Tan(17) = Opp
61.1461 =Opp
so the height of the radio mast is 61.1 meters ( rounded to nearest 10th )
Does this seem a bit easier when you think about how the parts of the trig functions fit on the triangles? :) ask if you have any questions

Step-by-step explanation:
What’s the equation of the line in fully simplified slope-intercept form
Answer:
y= -x - 8
Step-by-step explanation:
To write an equation in slope-intercept form, we naturally need both the slope and the y-intercept. Here, our y-intercept is -8, and our slope is -1. The general form of a line in slope intercept form is y = mx + b, where m is the slope and b is the y intercept. Using our values of m = -1 and b = -8 then gives us the equation y = -x - 8.
Write an equation that models this situation. At a sports banquet, 8 guests are seated at each of the 15 available tables. How many guests (x) are seated at the tables?
Answer: The equation that models this situation is:
x = 15 × 8 or x ÷ 8 = 15
Step-by-step explanation:
Let 'x' be the total number of guests who are seated at the tables.
If have to determine how many guests (x) are seated at the tables, all we need is to multiply the 15 with 8.
so the equation becomes
x = 15 × 8 or x ÷ 8 = 15
Therefore, the equation that models this situation is:
x = 15 × 8 or x ÷ 8 = 15
hope this helps good luck
If 2x - 3y = 24 and 3x + 4y = 2, what is the value of x - y?
Answer:
2x-3x=24____eqn 1
3x+4y=2____eqn 2
solve eqn 1 and 2 simultaneously using elimination method
eliminate x use the coefficients of x in the two equations to multiply each other i.e
3(2x-3y=24)
2(3x+4y=2)
6x-9y=72
6x+8y=4
eliminate x using the subtraction sign(-)
6x-6x-9y-(+8y)=72-4
-9y-8y=68
-17y=68
divide both side by the coefficient of y
y=68/-17
y=-4
put y=-4 in eqn 2
3x+4y=2
3x+4(-4)=2
3x-16=2
collect like term
3x=2+16
3x=18
divide both side by the coefficient of x
x=18/3
x=6
since we're asked to find x-y
6-(-4)
6+4=10

) A coin collection consisting of pennies, dimes, and quarters totals 45 coins. The number of
quarters is five more than twice the number of pennies and the number of dimes is four
more than the number of pennies. How much is the coin collection worth?/
9514 1404 393
Answer:
$7.14
Step-by-step explanation:
Let p, d, q represent the numbers of pennies, dimes, and quarters in the collection, respectively.
p + d + q = 45 . . . . . . . . there are 45 coins in the collection
2p +5 = q . . . . . . . . . . . . 5 more than twice the number of pennies
p + 4 = d . . . . . . . . . . . . . 4 more than the number of pennies
Substituting the last two equations into the first gives ...
p +(p +4) +(2p +5) = 45
4p = 36 . . . . . . . . . . . . . subtract 9
p = 9 . . . . . . . . . . . divide by 4
d = 9 +4 = 13
q = 2(9) +5 = 23
The value of the collection is ...
23(0.25) +13(0.10) +9(0.01) = 5.75 +1.30 +0.09 = 7.14
The coin collection is worth $7.14.

t a school. number of boys/number if girls =9/7. there are 116 more boys than girls. work out the total number of students at the school
Answer:
928
Step-by-step explanation:
Ratio of boys to girls is 9:7, so boys are 9/(9+7) = 9/16 of the total, and the girls are 7/16
the difference is 9/16-7/16 = 2/16 = 1/8, so
x * 1/8 = 116
x = 116*8 = 928

This hanger is in balance. (view image) There are two labeled weights of 4 grams and 12 grams. The three circles each have the same weight. What is the weight of each circle, in grams?
A. 3/8
B. 1
C. 8/3
D. 8
Answer:
c.) 8/3
Step-by-step explanation:
the two sides must weigh the same, or 12 grams.
the weights labelled x combined with the 4 grams weight should equal 12 grams.
the equation solved for x would be:
3x + 4 = 12
3x = 8
x = 8/3

Zack and Dave each bought some coins from jerry online. Dave bought 5 more coins than Zack bought
C. Explain why it’s not necessary to know how many coins Zack bought to determine how much more Dave paid than Zack paid
Answer & Step-by-step explanation:
number of Dave's coins = number of Zack's coins + 5
The question is asking to find the difference in prices paid (thus "more"), completely unrelated to the number of coins Zack bought as these two numbers are independent of one another. The difference in price can be found by simply multiplying the cost of one coin by 5.
