Find the length of ST
Andru [333]

Answer:

ST = 12

Step-by-step explanation:

By AA Similarity, triangles ASR and EST are similar.

The ratio of the lengths of the sides of triangle ASR to those of EST is 6/8 or 3/4.

\dfrac{SR}{ST} = \dfrac{3}{4}

Also,

SR + ST = 21

By a rule of proportions, you get

\dfrac{SR + ST}{ST} = \dfrac{3 + 4}{4}

\dfrac{21}{ST} = \dfrac{7}{4}

7ST = 4 \times 21

7ST = 84

ST = 12

Please help ‼️‼️ I’m doing functions
eduard
In this problem, you're looking for the value of t, so that f(t) = 48. That means if you put t into 5t-7, you'll get 48. To do this set up and solve an equation for t by setting 48 equal to 5t-7:
5t-7=48

Isolate the variable by adding 7 to both sides. 
5t=55

Divide by 5 on both sides to find t.
t=11

The answer is 11.

Ok here is a better pic I need help with it​
BartSMP [9]

Answer:

Step-by-step explanation:

First,You have to realize that if you multiply the amount of food by something, you multiply the amount of calories.  if some piece of food is 100 calories what happens if you eat 2?  you get 2 times that number of calories.  Same fi you eat half of one of that kind of food.  You get half the amount of calories.

Here he makes 1 1/2 (one and a half) times the amount.  Now, if this is confusing  you just need to realize that  multiplying by this is the same as multiplying by 1+1/2.  Say, again, a piece of food is 100 calories.  Multiplying it by this would look like the following.

100(1+1/2)

100*1 + 100*1/2

100+50

150

So if you ever have a mixed number like this  you could split it up into an addition problem and then distribute hat you're multiplying.  Another solution is to multiply by the improper fraction, which here is 3/2, so 100*3/2=150 as well.  Let me know if you don't get how to get the improper fraction or how to multiply fractions.

Now, super simple, just multiply the calories by that number.

310(1+1/2) = 310(3/2)

310 + 155 = 930/2

465 = 465

Kinda showed how to multiply by fractions, still if you don't get it let me know.
