8%*45.90=3.67

18%*45.90=8.26

Add, 45.90+8.26+3.67

Please help me with these please.

6. Answer: y = 5x - 11

Step-by-step explanation:

Parallel means "same slope". y = 5x - 2 is in the form y = mx + b,

so the slope (m) = 5

Next, input the point (x₁, y₁ = 2, -1) and slope (m = 5) into the Point-Slope formula:

y - y₁ = m(x - x₁)

y - (-1) = 5(x - 2)

y + 1 = 5x - 10

y = 5x - 11

7. Answer: $\bold{y = \dfrac{1}{3}x + 4}$

Step-by-step explanation:

Perpendicular means "opposite reciprocal slope". y = -3x + 7 is in the form y = mx + b, so slope (m) = -3 ⇒ m⊥ = $\frac{1}{3}$

Next, input the point (x₁, y₁ = 3, 5) and slope (m = $\frac{1}{3}$ ) into the Point-Slope formula:

y - y₁ = m(x - x₁)

$y - 5=\dfrac{1}{3}(x - 3)$

$y - 5 =\dfrac{1}{3}x - 1$

$y=\dfrac{1}{3}x + 4$

Suppose we draw 3 marbles from a jar containing 7 red and 5 blue marbles. At each stage, a ball is drawn and its color noted. Th

Vilka [71]

Answer:

The probability that the next two balls are blue is $\frac{5}{32}$

Step-by-step explanation:

There is a total number of 12 balls in the jar (7 Red and 5 blue), if the first marble drawn is a given, that is it is a Red marble, then following the instruction the Red marble and two more Red marbles are added. Therefore making the total number of marbles in the jar to be 14 marbles (9 red and 5 blue).

FIRST EVENT: So the probability of drawing the second marble to be a blue marble becomes = 5/14 [this is the number of blue marbles/ total number of marbles in the jar].

Thereafter the blue marble is returned and two more blue marbles are added to the jar making a total of 16 marbles (9 red and 7 blue}.

SECOND EVENT: So the probability of drawing the third marble to be a blue marble becomes = 7/16 [this is the number of blue marbles/ total number of marbles in the jar].

However, this is not the final answer because the first event and the second event must occur together, therefore, one has to multiply the first events probability and the second events probability to get the probability we are looking for.

So, the probability of picking the next two to be blue = 5/14*7/16 (seven can reduce the 14 to a 2 based on division)

Therefore the probability = 5/32 (the 2 multiplies the 16)

Jimmy's school is selling tickets to the annual dance

LiRa [457]

A= adult ticket c=child ticket
1. 6a+4c=88
12a+9c=186
2. so you need to multiply the top number by -2 so you can cancel out the 12a
-2(6a+4c=88)=. -12a-8c=-176
3. then you add them all together
12a+9c=186
-12a-8c=-176
——————————-
c=10
4. now you have to find ‘a’
6a+4(10)=88
6a+40=88
-40. -40
6a=48
divide both sides by 6
a=8
And your final answer should be (8,10)
hoped this helped:)
