A recipe requires 3 cups of flour to make 27 dinner rolls. How much flour is needed to make 9 rolls?Mandy runs 4 km in 18 min. She plans to run in a 15 km race. How long will it take her to complete the race?
Answers
Answer:
a)1 cup of flour
b)67.5 minutes
Step-by-step explanation:
a) A recipe requires 3 cups of flour to make 27 dinner rolls. How much flour is needed to make 9 rolls?
From the above question, we know that:
27 dinner rolls = 3 cups of flour
9 dinner rolls = x
Cross Multiply
27 rolls × x = 9 rolls × 3 cups
x = 9 rolls × 3 cups/27 rolls
x = 1 cup of flour
Hence, 1 cup of flour is needed to make 9 dinner rolls
b) Mandy runs 4 km in 18 min. She plans to run in a 15 km race. How long will it take her to complete the race?
From the above question:
4 km = 18 minutes
15km = x
Cross Multiply
4km × x = 15km × 18 minutes
x = 15km × 18minutes/4km
x = 67.5 minutes
Hence, in a 15km race , it would take her 67.5 minutes to complete her race.

Question: Determine The Value Of X.
Answers
9514 1404 393
Answer:
x = 78
Step-by-step explanation:
The base angles of an isosceles triangle are congruent, so the sum of angles is ...
x° +x° +24° = 180°
2x +24 = 180 . . . . . collect terms
x + 12 = 90 . . . . . . . divide by 2
x = 90 -12 . . . . . . . . subtract 12
x = 78
_____
Additional comment
The base angle of an isosceles triangle is always the complement of half the third angle. That angle's bisector is an altitude, so divides the isosceles triangle into two congruent right triangles.

To show -1 + (-6) on the number line, which directions would you move? *
5 points
right one unit, then left 6 units
Answers
Answer:
you would move left once, then left again 6 times. so 7 times to the left.
Step-by-step explanation:
You're moving left because you're working with negative numbers, so -1 would be the first step, and then just move 6 times more to the left. When you work with positives you do the same but to the right.
You will have to move left by 6 units.

33.: + 33 = 33. - 25
33.25 = 33r - 25
332 + 25 = 33r - 25
Which is no solution
Answers
Answer:
A, B & D
Step-by-step explanation:
Because if you subtract one of the constants from both sides then you should only have equal variables. In other words, both sides have to be identical in this situation.
33x-33= 33x + 25
33x = 33x + 58 No matter what you make x, the right will be 58 bigger than the right so there is no solution.
33x+33=33x+25
33x+8= 33x nope no solution
33x+25=33x+25
33x = 33x both sides identical so there is a solution
33x-25 = 33x +25
33x= 33x+50

Write the equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x
Answers
Answer:
[tex]\displaystyle y=-\frac{2}{3}x+3[/tex]
Step-by-step explanation:
We want to find the equation of the line that is parallel to:
[tex]\displaystyle y=-\frac{2}{3}x[/tex]
And passes through (-3,5).
First, we need to determine the slope of our new line.
Remember that parallel lines have the same slope.
Since the slope of our original line is -2/3, this means that the slope of our new line must also be -2/3.
Now, we can use the point-slope form given by:
[tex]y-y_1=m(x-x_1)[/tex]
We will let (-3, 5) be (x₁, y₁). By substitution:
[tex]\displaystyle y-(5)=-\frac{2}{3}(x-(-3))[/tex]
Simplify:
[tex]\displaystyle y-5=-\frac{2}{3}(x+3)[/tex]
Distribute:
[tex]\displaystyle y-5=-\frac{2}{3}x-2[/tex]
Add 5 to both sides. So, our equation is:
[tex]\displaystyle y=-\frac{2}{3}x+3[/tex]
Answer:
[tex]\displaystyle y = -\frac{2}{3}x + 3[/tex]
Step-by-step explanation:
5 = –⅔[–3] + b
2
[tex]\displaystyle 3 = b \\ \\ y = -\frac{2}{3}x + 3[/tex]
Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so –⅔ remains as is.
