Ms. K. is throwing a party with her favorite foods. Tacos cost $2.50 per tray and french fries cost $1.25 per pound. Ms. K. has $20 to spend on food. Let t be the number of taco trays Ms. K. buys and f be the number of pounds of french fries she buys when she spends all her money. Write an equation with the two variables.

Step-by-step explanation:

so, for me basically, as there are two food, I can do,.20$ ÷ 2= 10$

Then, I know that 10$ is the amount of money spent of each.

TACOS- EQ.1

t*$2.50= 10$

t=10$÷2.50=4

t=4

FRENCH FRIES-EQ.2

f*$1.25= 10$

f=10$÷$1.25= 8

f=8

NOW,

t*$2.50+ f*$1.25= $20

PUT EQUATION 1.

(4)*2.50+f*1.25=$20

PUT EQUATION 2

4*2.50+ 8*1.25= $20

I really hope this helps!!

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

d.) yes, because the volume of the cone is greater than the volume of the sphere
