Answers

Answer 1

Answer: x= -6 I'm not sure about this though.

Step-by-step explanation:

Answer 2

Answer:

[tex]4(5 + 2x) - 5 = 3(3x + 7)[/tex]

[tex]20 + 8x - 5 = 9x + 21[/tex]

[tex]15 + 8x = 9x + 21[/tex]

[tex]9x + 21 = 15 + 8x[/tex]

[tex]9x - 8x = 15 - 21[/tex]

[tex]x = - 6[/tex]

geometry, can u help????

Answers

Well since we’re given 2 angles, 62 and 58, we have enough information to solve the problem.

Since any triangles angles always add up to 180 degrees, we can simply add up 62 and 58 then subtract from 180.

62
+58
———
120

Now to find the last angle of the triangle you have to subtract 120 from 180 which is 60 degrees. This means x = 60.

However we’re not done, with this 60 we can now calculate y. Since the line is a 180 angle line! We can just subtract 60 from 180 which gives us 120.

The angle of y is 120

A girl weight increased by 12% between her tenth and four teen birthdays . If she weighed 45kg on her tenth birthday. What did she weigh on her fourteenth birthday

Answers

Ok so the first thing you are going to do is chang the percentage into a decimal. 12 percent would change into 0.12, because in order to change a percentage into a decimal you move the decimal two places to the left. Next you would multiply 0.12 by 45 which gives you 5.4. But we are not done yet. By multiplying 0.12 x 45 we find how much weight she has gained. So our next and final step should be add 5.4 to 45 which gives us 50.4. Therefore your answer should be 50.4kg

Answer: The answer would be e

First find where the line intercepts on the y axis, then find the slope of the line by looking at how much the line goes up from each point. In this case, the line goes up by 2 and across by 1, so your slope will be 2/1 which is 2. (If the line went down, the slope would be -2/1 which is -2) Then you can plug in the numbers for the equation for y-intercept form y=mx+b which gives you y=2x+2

Just trying to win the CONTEST BUT GOOOOD LUCK

Answer:

56 units, 84 units, 56 units, 140 units

Step-by-step explanation:

Since you have the ratios, you can multiply each by x, because you do not know the actual values.

2x+3x+2x+5x=336

12x=336

÷12  ÷12

x=28

Then, plug in the values of x.

So 2*28= 56

3*28=84

2*28=56

5*28=140

Can someone please help me pleaseeee!

Answers

Answer:

y=-1.7x+8

Step-by-step explanation:

An equation of a line is y=mx+c

m is the gradient and c is the y intercept, which is where the line intercepts y.

you work out m getting two points and then subtracting y - y ÷ x - x

So in this graph, if we chose points (6,-2) and (3,3) then we would do this equation.

[tex] \frac{3 - - 2}{3 - 6} = \frac{5}{ - 3} = - 1.7[/tex]

So m = -1.7

c = 8 because it goes through 8 in y.

So the equation is y=-1.7x+8

Billy wants to find out which cafeteria food is the favorite in his school for students. He surveys 100 students. 29 students select sub sandwiches, 35 select steak and gravy, and 36 select fried chicken. if you select one of these students. What is the probability it will be a student who prefers chicken


Answer choices
A. 7/20
B. 9/25
C. 40%
D.29/100​

Answers

Answer:

36% or  9/25

Step-by-step explanation:

35+36+29=100 so 100-35-29=64 and 36 are left so you divide 9/25 and you get 0.36 and you put it into a percentage and the answer is 36% or  9/25.

The probability it will be a student who prefers chicken is, 36/100.

What is probability?

Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. The possibility that an event will occur is measured by probability.

Probability of Event = Favorable Outcomes/Total Outcomes = X/n

Given that,

He surveys 100 students,

29 students select sub sandwiches,

35 select steak and gravy,

and 36 select fried chicken

The probability of selecting a student who prefers fried chicken can be found by dividing the number of students who prefer chicken by the total number of students surveyed:

36/100 = 36%.

This can also be expressed as a decimal or a percentage:

0.36 or 36%.
