Answer:
[tex]1\ can = 140g[/tex]
Step-by-step explanation:
Given
[tex]420 g = 3\ cans[/tex]
Required
Determine the number of grams in 1 can
[tex]420 g = 3\ cans[/tex]
Reorder
[tex]3\ cans = 420 g[/tex]
Divide both sides by 3
[tex]\frac{3\ cans}{3} = \frac{420 g}{3}[/tex]
[tex]1\ can = 140g[/tex]
Hence;
There are 140 grams in 1 can

The solution of the given inequality.
Solution:
We have,
[tex]x-(5-3x)\leq 2x-1[/tex]
[tex]x-5+3x\leq 2x-1[/tex]
[tex]4x-5\leq 2x-1[/tex]

Carla is ordering pizzas for delivery. Each pizza costs $8, and there is a $6 delivery charge for the order. Write the function f(x), that Carla can use to determine the amount she will pay for having x pizzas delivered.
Answer:
8x+6
Step-by-step explanation:
Because each pizza is $8 you would have to multiply 8 by the amount of pizzas. Then you add the six because you only pay for the delivery charge once.
MY 1st QUESTION, WILL GIVE BRAINILIST!
Scott's retirement party will cost $8 if he invites 4 guests. What is the maximum number of guests there can be if Scott can afford to spend a total of $14 on his retirement party? Solve using unit rates.
7, because 8/4 = 2 which means that 1 guest = $2. So if we do 14 / 2 to see how many guests that would be, it's 7.
Answer:
7
Step-by-step explanation:
Well if it's $8 for 4 people then you have to divide to get the rate:
$8/4 = [tex]\frac{2}{person}[/tex]
now you can divide the disired amount to get the number of people:
$14/ [tex]\frac{2}{person}[/tex] = 7 people
During a special sale, all video games cost $26 and all movies cost $14. Derrick plans to spend some or all of his $220 in birthday money on these movies and video games. Let "x" represet the number of games Derrick can buy and "y" represent the number of movies he can buy. Write the inequality that describes this situation in standard form.
Answer:
[tex]13x+7y\leq 110[/tex]
Step-by-step explanation:
Let "x" represents the number of games Derrick can buy and "y" represents the number of movies he can buy.
Cost of all video games = $26
Cost of all movies cost = $14
Total amount with Derrick = $220
So,
cost of [tex]x[/tex] video games + cost of [tex]y[/tex] movies [tex]\leq[/tex] 220
Therefore, the inequality is [tex]26x+14y\leq 220[/tex]
Divide this inequality by 2
[tex]13x+7y\leq 110[/tex]

What’s the unit rate of 2 1/3 miles in 2 hours
Answer:
7/6 miles
Step-by-step explanation:
As, Distance for 1 hour = x
For 2 hours = 2 1/3
For 2 hours = 2(x)
So, 2(x)= 2 1/3
2(x)= 7/3
So, x = 7/3 ÷ 2
So x= 7/3 x 1/2
Therefore, x = 7/6
Final answer= 7/6 miles per hour

Based on a graph below which sequence of transformation is needed to carry ABCD onto its image A’B’C’D?
Given:
The vertices of ABCD are A(2,3), B(5,6), C(8,6) and D(8,3).
The vertices of A'B'C'D' are A'(-2,6), B'(-5,3), C'(-8,3) and D'(-8,6).
To find:
The sequence of transformation is needed to carry ABCD onto its image A’B’C’D.
Solution:
The vertices of ABCD are A(2,3), B(5,6), C(8,6) and D(8,3).
If figure ABCD translated by the rule, [tex](x,y)\to (x,y-9)[/tex], then
[tex]A(2,3)\to A_1(2,-6)[/tex]
[tex]B(5,6)\to B_1(5,-3)[/tex]
[tex]C(8,6)\to C_1(8,-3)[/tex]
[tex]D(8,3)\to D_1(8,-6)[/tex]
Then the figure rotated 180 degrees clockwise about the origin. So,
[tex](x,y)\to (-x,-y)[/tex]
[tex]A_1(2,-6)\to A'(-2,6)[/tex]
[tex]B_1(5,-3)\to B'(-5,3)[/tex]
[tex]C_1(8,-3)\to C'(-8,3)[/tex]
[tex]D_1(8,-6)\to D'(-8,6)[/tex]
So, the required sequence of transformation that is needed to carry ABCD onto its image A’B’C’D is " A translation by the rule [tex](x,y)\to (x,y-9)[/tex] and then a 180° clockwise rotation about the origin".
Therefore, the correct option is D.

Answer:
ΔABD ≅ ΔCDB
Step-by-step explanation:
Since a = 3, we can sub 3 into the expressions and then get a value for each side length.
AB: 3 + 7 = 10
BC = 16
CD: 12 - 2 = 10
DA: 18 - 2 = 16
Hence:
AB = CD (both have sidelengths of 10)
AD = CB (both have sidelengths of 16)
BD = BD (common line)
Therefore: ΔABD ≅ ΔCDB Q.E.D.

state whether the percent of change is a percent of increase or a percent of decrease. Then find the percent of change. original: 75, new:84
Answer:
The percentage of change is an increase of 12% from the original
Step-by-step explanation:
The percentage of change is a percentage of increase because the new value is greater than the original.
To find the percentage of change, we can divide the new value by the old which will give us the amount it increased by in decimal form, which we can simply multiply by 100 to find percentage:
84/75=1.12
1.12x100 = 112
The new value is 112% of the original, this means that the percentage of change is an increase of 12% from the original.
Hope this helped!
Answer:

Step-by-step explanation:

[tex]y=-\frac{1}{4} x-1[/tex]
Step-by-step explanation:
[tex]y=mx+b[/tex]
where m = slope, and b = y intercept
The y intercept is -1. That is because the given line intersects the y axis at the point (0,-1)
The slope is -1/4
That is because it goes up one, and right -4. That means it goes up 1 and left 4.
Solve x-6y = 13 for y.
Answer:
y = 1/6x -13/6
Step-by-step explanation:
x-6y = 13
Subtract x from each side
x-x-6y =-x+ 13
-6y = -x+13
Divide each side by -6
-6y/-6 = -x/-6 + 13/-6
y = 1/6x -13/6
