Darnell ran 550 yards in 3 minutes. At this rate, how many yards can he run in 6 minutes?
Answer:
Darnell can run 1100 yards in 6 minutes
Step-by-step explanation:
There are 2 ways you can solve this
Method 1: You would have to divide 550 by 3 which you would get about 183, (the exact answer is very long so I recommend using a calculator). Then you multiply that by 6 to get 1100.
Method 2: This one would probably be easier. Since 3 x 2 is 6 then you can multiply 550 x 2 to get 1100.
I hope this helps!
Answer:
1100 yards
Step-by-step explanation:
Write it as an equation
550/3 = x/6
Cross multiply :
550 * 6 = 3x
3300 = 3x
x = 1100

Answer:
Carole's situation : 2x + 11y = 196
Michele's situation: 10x + 11y = 276
Step-by-step explanation:
If x = cost of 1 cupcake, then 2x = cost of 2 cupcakes and 10x = cost of 10 cupcakes, et.
If y = cost of 1 sugar cookie, then 11y = cost of 11 sugar cookies.
Carole's situation : 2x + 11y = 196
Michele's situation: 10x + 11y = 276
(-1,11) reflected over the y axis
(-3,-9) reflected over the y axis
(2, -7 reflected over the y axis
Answer:
See explanation
Step-by-step explanation:
Reflecting over the y axis does not change the Y value. It multiplies the x value by -1.
So (-1,11) is (1,11)
And (-3,-9) would become (3,-9)
And (2,-7) would become (-2,-7)

Answer:
[tex]3\sqrt{3}x[/tex]
Step-by-step explanation:
Expand √27x² in such a way that it is the :-
Product of at either two or more perfect square numbers or,Product of two or more numbers out of which one (or more) is a perfect square number.So ,
[tex]\sqrt{27x^2} = \sqrt{9 \times 3 \times x^2}= 3 \times \sqrt{3} \times x = 3\sqrt{3}x[/tex]

Solve the inequalities. -3y> 36
Answer:
y<-12
Step-by-step explanation:
-3y>36 divide both sides of the inequality by -3 and flip the inequality sign
-3y÷(-3)<36÷(-3) any expression divided by itself equals 1
y<36÷(-3) which equals to y<-12
answer choices 72 76 86 65
Look at the picture. Solve for y
Answer:
y = 5
Step-by-step explanation:
Equation:
m<DGF = m<DGE + m<EGF
Given:
m<DGF = 12y - 5
m<DGE = 5y + 6
m<EGF = 24
Work:
m<DGF = m<DGE + m<EGF
12y - 5 = 5y + 6 + 24
12y - 5 = 5y + 30
12y - 5y = 30 + 5
7y = 35
y = 5

Answer:
where is the diagram?
Step-by-step explanation:
please help!! 40 points . if you guess or just comment to take points i will make sure your account gets banned, thanks! i want a small simple explanation.
Answer:
1) m<DBE= 140
2)m<EBD= 30
Step-by-step explanation:
1) 5x-60= x+20
4x= 80
x= 20
plug in the x into the equation: (x+20)---> (20+20)=40
180-40= 140
2) 4x-2+20x-10= 180
24x= 192
x=8
plug in the x into the equation: (4x-2)----> 4(8)-2----> 32-2= 30

what is an equation in point slope form of the line that passes through (-5, -4) and has a slope of 3
Answer:
y + 4 = 3(x + 5)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 3 and (a, b) = (- 5, - 4) , then
y - (- 4) = 3(x - (- 5) ) , that is
y + 4 = 3(x + 5)
Hi there! The point-slope is shown in the picture.
Both x1 and y1 are the ordered pairs or coordinate points. Not to be confused with the x and y, they are just for to form an equation of a line.
As we know, m is defined as slope.
What we have now are:
the value of slope (m = 3)(x1, y1) = (-5,-4)Point-Slope equationSubstitute the value of the point and slope in the equation.
[tex] \large{y - ( - 4) = 3(x - ( - 5))} \\ \large{y + 4 = 3(x + 5)}[/tex]
Answer
The point-slope form for this question is y+4=3(x+5)Work out the value of 3.1^4

AABC is a right triangle. AB=____
Since ABC is a right triangle, we can use Pythagorean Theorem to solve for side AB.
Pythagorean Theorem: a^2 + b^2 = c^2
4^2 + 7^2 = c^2
16 + 49 = c^2
65 = c^2
c = 8.06
Hope this helps!! :)
Answer:
8.06
Step-by-step explanation:
Well the formula for this is [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
The sides given are called the opposite and the adjacent, which, in this formula correspond to a and b. What you are trying to find is called the hypotenuse, and in this formula, c.
First you need to square a and b, like in the formula:
[tex]4^{2}[/tex] = 16
[tex]7^{2}[/tex] = 49
Now you add these together to find [tex]c^{2}[/tex]:
16 + 49 = 65
So [tex]c^{2}[/tex] is 65, and to find c you need to square root that:
[tex]\sqrt{65}[/tex] = 8.0622577...
So its approximately 8, and more accurately 8.06

Answer:
x = 3
Step-by-step explanation:
5(5 + 19) = 6(6 + 4x + 2)
5(24) = 36 + 24x + 12
120 = 48 + 24x
72 = 24x
x = 3
simplify the question
Answer:
[tex] \frac{2}{x - 3} - \frac{12}{ {x}^{2} - 9} \\ = \frac{2}{x - 3} - \frac{12}{(x - 3)(x + 3)} \\ = \frac{2(x + 3) - 12}{( {x}^{2} - 9)} \\ = \frac{2x - 6}{( {x}^{2} - 9)} \\ = \frac{2(x - 3)}{(x - 3)(x + 3)} \\ = \frac{2}{x + 3} [/tex]
