Answer:

The equation to solve to find the number of yellow marbles =

3y + y = 500

4y = 500

The number of yellow marbles = 125

Step-by-step explanation:

Let the number of

Blue marbles = x

Yellow marbles = y

A large jar contains 500 marbles.

x + y = 500

All of the marbles in the jar are either blue or yellow, and there are 3 times as many blue marbles as yellow marbles.

3y = x

Hence, we substitute 3y for ymx in the above equation

3y + y = 500

4y = 500

y = 500/4

y = 125

The number of yellow marbles = 125

FEDY is a parallelogram. What is the measure of angle F?
MArishka [77]

Answer:

65 degrees

Step-by-step explanation:

Break the parallelogram up into two triangles. Angle E is 70 degrees and 45 degrees because of the property of equal opposite angles. So E 45 degrees Y 70 degrees and if you add the two up you get 115 degrees. There are 180 degrees in a triangle, so 180-115=65.

The cost of 5 diesels is $1025. Calculate the cost of 17diesels
Talja [164]
To calculate the cost of 1 diesel divide the cost of 5 by 5 to get 1 or $1025/5=205
To get the cost of 17, multiply the cost of 1 which is 205x17=3,485 so 17 is $3,485

5x + 15 = 2x +3<br> x = what
gladu [14]

5x + 15 = 2x + 3 \\ 5x + 15 + 3 = 2x \\ 5x + 18 = 2x \\ 18 = 2x - 5x \\  - 3x = 18 \\ x =  \frac{18}{ - 3}  \\  \\ x =  - 6

<h2><u>x = (-6)</u></h2>

Given the system of linear equations.
Degger [83]

Part(A):

To solve the system of Linear equations using Substitution:

x+y=7 \\ 2x+y=5

Consider the first equation, x+y=7 implies x=7-y

\mathrm{Subsititute\:}x=7-y

2\left(7-y\right)+y=5

14-2y+y=5

14-y=5

\mathrm{Subtract\:}14\mathrm{\:from\:both\:sides}

14-y-14=5-14

-y=-9

\mathrm{Divide\:both\:sides\:by\:}-1

y=9

\mathrm{For\:}x=7-y

\mathrm{Subsititute\:}y=9

x=7-9=-2.\mathrm{The\:solutions\:to\:the\:system\:of\:equationts\:are:}

y=9,\:x=-2

PArt(B): Use a graph to verify your answer to the system:

Using Desmos graphing calculator, graph the two equations.
