a) 0.10 x $17.00 = $1.7
$17.00 - $1.7 = $15.30
You will save $15.30 on the DVD
b) $15.30 + $17.00 = $32.30
You will spend $32.30 on the DVD
Lacey picks blueberries and raspberries from her garden. She has 1/5 as many pounds of blueberries as raspberries. If she picks 1 4/5 pounds more blueberries, she will have equal weights of berries. Let x represent the weight of raspberries. Which equations could be used to find the weight of blueberries Lacey has?
Answer:
1/5 + 1 4/5 = x.
Step-by-step explanation:
b=1/5x and b+[tex]1\frac{4}{5}[/tex]=x are the equations used to find the weight of blueberries Lacey has. 9/20 is the weight of blueberries.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Lacey picks blueberries and raspberries from her garden.
Let b =weight of Blueberries
x=weight of raspberries
Lacey has 1/5 as many pounds of blueberries as raspberrie
b=1/5x..(1)
[tex]1\frac{4}{5}[/tex] pounds more blueberries, she will have equal weights of berries
b+[tex]1\frac{4}{5}[/tex]=x
b=x-1 4/5
b=x-9/5
So substitute b in equation 1
x-9/5=1/5x
x-1/5x=9/5
x(1-1/5)=9/5
x(4/5)=9/5
x=9/4
x=[tex]2\frac{1}{4}[/tex]
b=9/4-9/5
b=45-36/20=9/20
Hence b=1/5x and b+[tex]1\frac{4}{5}[/tex]=x are the equations used to find the weight of blueberries Lacey has. 9/20 is the weight of blueberries.

Of the 36 students in the class, 8 of them are boys. If one student is picked at random, what is the probability that the student will be a boy?
WILL GIVE BRAINLIEST!
Answer:
B
Step-by-step explanation:
So first off, the question is saying to find the difference so that means you subtract. Then it says that the number has to be at least 15 so that means that the inequality sign is greater than or equal to. Since you are subtracting you must add 13 to both sides to cancel it out and x would equal 15+13. So that makes the inequality true since the total is 28. You see if the answer would've been the first one then, the inequality would not have been true since the number 2 is not at least the number 15. Hope this helps
You can use the interactive graph below to find the solution.
y = x - 4
y = 4x + 2
x = ______
y = ______
helppp
it then shows the graph shown in the picture!
Answer:
x = -2
y = -6
Step-by-step explanation:
System of equations given in the question are,
y = x - 4 ---------(1)
y = 4x + 2 -------(2)
For equation (1)
y-intercept of the line → (0, -4)
x-intercept of the line → (4, 0)
Joining these points we can get the graph of the line represented by equation (1).
Similarly, for equation (2),
y - intercept of the line → (0, 2)
x- intercept of the line → (-0.5, 0)
Joining these points we will get the graph of the equation (2).
Solution of these equations will be the point of intersection or common points of both the equations.
From the graph attached,
Solution of the system of equations will be → x = -2
y = -6
-(7-9)z-6z=8(-6+2) solve for z
can I see the process I know the answer is 8 I just don't understand the process
Answer:
(-(7-9))(z)-6z= 8(-6+2)
Simplify
-(-2)(z) -6z =8(-6+2)
Multiply 8*-6 and 8*2
2z -6z= -48+16
Combine like terms
2z+-6z =-32
-4z=-32
Divide both sides by -4
z=8

One serving of special sundae is made up of one third mint ice cream one third chocolate and one third vanilla. How much vanilla ice cream is in a half serving
Answer:
[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
Given: One serving of special sundae is made up of one third mint ice cream one third chocolate and one third vanilla.
To find: Ratio of vanilla ice cream is in a half serving
Solution:
Ratio of mint ice cream in one serving [tex]=\frac{1}{3}[/tex]
Ratio of chocolate ice cream in one serving [tex]=\frac{1}{3}[/tex]
Ratio of vanilla ice cream in one serving [tex]=\frac{1}{3}[/tex]
Here, [tex]\frac{1}{3} +\frac{1}{3} +\frac{1}{3} =1[/tex]
Therefore,
Ratio of vanilla ice cream is in a half serving [tex]=\frac{1}{3}(\frac{1}{2})=\frac{1}{6}[/tex]

Answer:
y = (2/3)x + 7
Step-by-step explanation:
Slope intercept form is y = mx +b
1) We start off with y =
2) m = slope. Since we know that the slope is 2/3 we can plug it in. y = 2/3x
3) b is y-intercept which = 7.
Put it all together: y = 2/3 x + 7
