Jane bought a 20-ounce smoothie that contains 350 calories plus some apples at about 95 calories each. Lin bought a 255-calorie fruit drink plus some bananas at about 105 calories each. If Jane and Lin each bought 5 pieces of fruit, whose purchase contains more calories?
Answer:
Janes purchase had more calories.
Step-by-step explanation:
Why?
Well, for Jane you do 350+(95times 5) = $825
For LIn you do 255+(105times 5) = $780
So... Jane has more.

Penny has 14 coins, all nickels, dimes, and quarters, totaling $2.50. She has twice as
many dimes as nickels, and twice as many quarters as dimes. How many dimes does
she have?
a.4
b.5
c.6
d.3
Answer:
Step-by-step explanation:
D = 2N
Q = 2D
Q = 4N
N = ??
Q + D + N = 2.50
(4N) + (2N) + N = 2.50
7N = 2.50
D = 2N
7D = 14N

150 - 1/2s = 120 + 1/4s
Answer:
s=40
Step-by-step explanation:
Combine s and 1/2.
150−s/2=120+1/4s
Combine 1/4and s.
150−s/2=120+s/4
Move all terms containing s to the left side of the equation.
150−3s/4=120
Move all terms not containing s to the right side of the equation.
−3s/4=−30
Multiply both sides of the equation by −4/3.
−4/3 x (−3s/4)=−4/3 x−30 => S=40
Answer:
40
Step-by-step explanation:
First, get all the s on the same side
add 1/2s to both sides
[tex]150 = 120 + \frac{3}{4}s[/tex]
Next, subtract 120 from both sides to get s by itself
[tex]30 = \frac{3}{4}s[/tex]
Now, multiply both sides by 4 to get rid of the fraction
120 = 3s
Lastly, divide both sides by 3 to get s by itself
s = 40
Solve the simultaneous equations below. Show your work clearly,
a)
y-2x = 6
A
y + 2x = 6
Answer:
The solution of the given two equations
( x, y) = (0,6)
Step-by-step explanation:
Step(i)
Given equations are
y - 2x = 6 ...(i)
y + 2x = 6 ...(ii)
Adding (i) and (ii) equations, we get
y - 2x + y +2x = 6+6
2 y = 12
y =6
Step(ii):-
substitute y =6 in equation (i). we get
y - 2x =6
6 - 2x =6
6-6 =2x
0 = 2 x
x = 0
The solution of the given two equations
( x, y) = (0,6)

The length of a rectangle is shown below: On a coordinate grid from negative 6 to positive 6 on the x-axis and on the y-axis, two points A and B are shown. The point A is on ordered pair negative 2, 3, and the point B is on ordered pair 3, 3. If the area of the rectangle to be drawn is 30 square units, where should points C and D be located, if they lie vertically below A and B, to make this rectangle?
Answer:
C = (3, -3), D = (-2, -3)
Step-by-step explanation:
The distance between two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] on the coordinate plane is given by:
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Points ABCD form a rectangle with an area of 30 unit². Points A and B are located at A(-2, 3) and B(3, 3). The distance between A and B is:
[tex]|AB|=\sqrt{(3-(-2))^2+(3-3)^2}=5\ units[/tex]
|AB| = width = 5 units
Area of ABCD = |AB| * |BC|
30 = 5 * |BC|
|BC| = length = 6 units
Let point C be located at (c, d). Since point C is below point B, hence the c coordinate of point B would be the same as that of C. Hence C = (3, d)
[tex]|BC|=\sqrt{(3-3)^2+(d-3)^2} \\\\\sqrt{0+(d-3)^2}=6\\\\square\ both\ sides:\\\\(d-3) ^2=36\\\\take\ square\ root\ of\ both\ sides:\\\\d-3=\pm 6\\\\d=6+3\ or\ d=-6+3\\\\d=9\ or\ d=-3\\\\[/tex]
Since point C is vertically below point B, hence the y coordinate would be negative
d = -3
C = (3, -3)
Point D would have the same y coordinate as point C since they are on the same horizontal line. Also, point D would have the same x coordinate as point A since it is vertically below point A. Hence:
D = (-2, -3)

A plane travels a distance of 22,000km in a time of 3.6 hours. What is its average speed rounded to the nearest whole number
Answer:6111 km/hr
Step-by-step explanation:
Given
Distance travels by plane d=22,000 km
time taken t=3.6 hours
[tex]\text{distance}=\text{speed}\times\text{time}[/tex]
average speed
[tex]v_{avg}=\dfrac{22,000}{3.6}=6111.11\approx 6111\ km/hr[/tex]

lan needs to solve 23 = y + 40. What is the step that shows the inverse operation needed to solve this equation. Find the value of y.
Y=
Answer:
y=17
Step-by-step explanation:
We move all terms to the left:
23-(y+40.)=0
We add all the numbers together, and all the variables
-(y+40)+23=0
We get rid of parentheses
-y-40+23=0
We add all the numbers together, and all the variables
-1y-17=0
We move all terms containing y to the left, all other terms to the right
-y=17
y=17/-1
y=-17
