Hello cayleahm253!

There are 35 boys in 6th grade. The number of girls in 6th grade is 40. Emma says that means the ratio of the number of boys in 6th grade to the number of girls in 6th grade is 3:4. Is Emma correct? If not, what is the correct answer?
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Okay, so we can see from the question that there are 35 boys & 40 girls in the 6th grade. So the ratio of boys is to girls will be 35:40.

Solving...
[tex]35 : 40 \\ = \frac{35}{40} \\ \\ \sf \: Cancel \: out \: 35 \: and \: 40 \: to \: get \: 7 \: and \: 8.\\ \\ = \frac{7}{8} \\ = \huge \boxed{\boxed{\bf \: 7 : 8}}[/tex]

So, the correct ratio is not 3:4. Instead it's 7:8.__________________

| 4x-13 | = 5x+4
Solve
Answers
Answer:
x = 1
Step-by-step explanation:
The absolute value always gives a positive value. However, the expression inside can be positive or negative , so
4x - 13 = 5x + 4 ( subtract 4x from both sides )
- 13 = x + 4 ( subtract 4 from both sides )
- 17 = x
OR
- (4x - 13) = 5x + 4 , simplify left side
- 4x + 13 = 5x + 4 ( subtract 5x from both sides )
- 9x + 13 = 4 ( subtract 13 from both sides )
- 9x = - 9 ( divide both sides by - 9 )
x = 1
As a check
Substitute these values into the equation and if both sides are equal then they are solutions.
x = - 17
left side = | 4(- 17) - 13 | = | - 68 - 13 | = | - 81 | = 81
right side = 5(- 17) + 4 = - 85 + 4 = - 81 ≠ 81
Then x = - 17 is an extraneous solution
x = 1
left side = | 4(1) - 13 | = | 4 - 13 | = | - 9 | = 9
right side = 5(1) + 4 = 5 + 4 = 9
Then solution is x = 1

Answer:
y=-3.75x-2.25
Step-by-step explanation:
Step 1: Find the slope (m) using the Slope Formula, Y2-Y1/X2-X1
(-6)-(9)/(1)-(-3) = -15/4 = -3.75
Step 2: Find the Y-intercept (b) using the Slope Intercept Formula, y=mx+b
9=-3.75*(-3)+b
9=11.25+b
b=9-11.25
b=-2.25
Step 3: Plug in your slope (m) and Y-intercept (b) values into the Slope Intercept Formula, y=mx+b
y=-3.75x-2.25
Step 4: Plug your X values into the formula, you should get your Y values after solving
y=-3.75(-3)-2.25=11.25-2.25=9 (-3, 9)
y=-3.75(1)-2.25=-3.75-2.25=-6 (1, -6)

We have to give that,
A mixed fraction is,
⇒ 3 6/7
Now, We can change the fraction into an improper fraction as,
⇒ 3 6/7
⇒ (3×7 + 6)/7
⇒ (21 + 6)/7
⇒ 27/7
Therefore, an improper fraction in the lowest term is,

Answer:
answer for 10th question is 121
Step-by-step explanation:
2(a+b)+a+b/2+(a+b)^2-4
=2(10)+10/2+(10)^2-4
=20+5+100-4
=125-4
=121
Answer:
10. 121 11. Hamburger = $1.43
Step-by-step explanation:
2(a + b) + (a + b)/2 + (a + b)² - 4
2(10) + (10)/2 + (10)² - 4
20 + 5 + 100 - 4
25 + 100 - 4
125 - 4 = 121
11. Let H = Hamburger and Soft Drink = D
H + D = $2.23
2 H + 3D = $5.26
H + D = $2.23 Solve for D
D = $2.23 - H
2H + 3D = $5.26 Now substitute the value of H into the second equation.
2H + 3($ 2.23 - H) = $5.26
2H + $6.69 - 3H = $5.26
-H + $6.69 = $5.26
-H = - $1.43
H = $1.43

Reflect the image over the y-axis and then translate 8 units down. What are the coordinates for C’?
Answers
Answer:
(-7, -7)
Step-by-step explanation:
1. Let's ONLY focus on point C.
2. The algebraic rule for reflecting across the y-axis is (x, y) -> (-x, y).
Since point C is on the coordinate (7,1), when reflecting it across the y-axis, it's going to turn into (-7,1).3. The algebraic rule for translating 8 units down is (x, y) -> (x, y - 8).
Since C is on (-7,1), when we translate it 8 units down, we'll get C' as (-7, -7)Therefore, the coordinates for C' are (-7, -7).
