Answer:
the number of meals that yolanda sold is 24
Step-by-step explanation:
The computation of the number of meals that yolanda sold is shown below:
Given that
The total meals sold is 122
Let yolanda meals be x
So jackie meals would be 3x
And, thomas meals be x + 2
So according to this
the equation is
x + 3x + x + 2 = 122
5x + 2 = 122
5x = 120
x = 24
Hence, the number of meals that yolanda sold is 24
The distance between dchool a and school b is 360 kilometers away If a bus leaves school. A at 9 30. And reaches school b at 230 what is the speed in hilometers per hour
Answer:
v = 72 km/h
Step-by-step explanation:
Given that,
The distance between school a and b is 360 km.
A bus leaves school a at 9:30 and reaches school b at 2:30
Total time, t = 5 hours
We know that, the speed of an object is equal to the total distance divided by total time taken.
So,
v = d/t
[tex]v=\dfrac{360\ km}{5\h}\\\\v=72\ km/h[/tex]
So, the required speed is 72 km/h.
Solve for x and then find the measure of B
Answer:
x=6
b= 126
Step-by-step explanation:
8x+78 = 2x+114
8x-2x = 114-78
6x=36
x=6
--------
b=2x6+114
b= 126

-(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]

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.

Someone buys 6 cakes for 8$ each he sells them for ten each then he got 8 more and selled them for 10$ how much money does he have left???
Answer: $28
Step-by-step explanation:
The person bought 6 cakes for $8 which reduces his money by:
= 6 * 8
= -$48
He then sells them for $10 each so the money made was:
= 10 * 6
= $60
He then buys 8 more for the same price which will reduce his money by:
= 8 * 8
= -$64
He sells these 8 for $10 so the money made was:
= 8 * 10
= $80
Total money left is therefore:
= 60 + 80 - 48 - 64
= $28

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

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

Investment account 1 starts with a balance of $200 and doubles ever year. Investment account 2 starts with a balance of $1,000 and increases by $100 each year. How long does it take for each account to double?
Answer:
Account 1 would take 1 year or 12 months to double. Account 2 would take 10 years for its ammount to double.
Step-by-step explanation:
Since Account 1 doubles each year, it would only take one year to reach the double. For Account 2, since it only increases by $100 each year, it would take 10 years to double. If 1,000 is divided by 100 we would be left with 10. By increasing the ammount by 100 for 10 years, we would be left with 1,000 after this alotted time.
Answer:
Account 1 would take 1 year or 12 months to double. Account 2 would take 10 years for its amount to double.
