Mathematics

dlinn [17]3 years ago
3 0

Answer:

x=0 and y=4 thats where the points meet

Step-by-step explanation:

solution of x and y:

both equations equal to y so you can put them together

3/5x+4=-x+4

separate the variables and numbers...

1.6x=0

x=0

y=4

if ur using a graph, use the y intercept (0,4) for your first point

then, using y=-x+4, make -x a fraction -1/1

by using rise/run go down one unit from (0,4) since its negative 1

then one unit to the right from where you are

you should be able to connect the points for the first equation

find the second equation on your own now:)

Kensington City Cafe recently introduced a new flavor of coffee. They served 28 grande cups
Dmitrij [34]

Answer:

jumbo 23 oz, grande 16 oz

Step-by-step explanation:

Use g for grande and j for jumbo

The first equation: 28g + 33j = 1207

The second equation: 28g + 53j = 1667

Subtract the first from the second

   28g + 53j = 1667

-   28g + 33j = 1207

Equal 20j = 460

j = 23

Put 23 in for j in either equation and solve for g:

28g + 33(23) = 1207

28g + 759 = 1207

28g = 448

g = 16

What is .65% of 160? Show your work
vladimir2022 [97]
0.65/100 = x/160 Ok, until now?

You then find the cross product: (0.65)(160) = 100x

104 = 100x        104/100 = 1.04

So x = 1.04 and it is also 0.65% of 160


Hope this helps!
