Answer:

See explanations below

Step-by-step explanation:

a) 1/4+5/4

= (1+5)/4

= 6/4

= 3/2

b) 23/17+11/17

= (23+11)/17

= 34/17

= 2

c) 16/93+15/93

= (16+15)/93

= 31/93

= 1/3

d) 11/14+23/14

= (11+23)/14

= 34/14

= 17/7

e) 3/16+15/16

= (3+15)/16

= 18/16

= 9/8

f) 1 1/8 + 1 3/8

= 9/8 + 11/8

= (9+11)/8

= 20/8

= 5/2

g) 1 3/10+3 1/10;

= 13/10+31/10

= (13+31)/10

= 44/10

h) 2 3/5+3 2/5

= 13/5+17/5

= (13+17)/5

= 30/5

= 6

Can someone help me with the top 1-3. Using similar figures subject
katen-ka-za [31]
Answer: <M corresponds to <J
               <L corresponds to <O
               JL corresponds to MO 

To find the corresponding angles:
1. Look at the figures. 
<M is to <J, <N is to <K, and <O is to <L.

2. Look at the similarity statement. 
ΔMNO ~ ΔJKL. <M is to <J because they are the first letters.
ΔMNO ~ ΔJKL. <N is to <K because they are second letters.
ΔMNO ~ ΔJKL. <O is to <L because they are third letters.

Apply these two methods to find the corresponding sides.

A fruit seller packed some apples into 15 small cartons and 20 big cartons. Each big carton contained 15 more apples than each s
ehidna [41]

Answer:

720 apples

Step-by-step explanation:

Let A be the number of apples in the small pack.

QTY for Small Cartons is 15A,

QTY for Big Cartons is 20(A+15) = 20A+300

From small cartons makes 25% or 1/4 of total, means the big carton makes 75% of total, or 3/4 of total. This also means the qty in big carton is 3 times of small carton

20A+300 = 3X (15A)= 45A

300 = 25A

A=12

Altogether = 15A+(20A+300) = 720 Apples

Best explained and correct answer gets brainliest!!
Semmy [17]
The answer is D, here’s why:

You know the slope-intercept form is y=mx+b
mx being the slope and b being the y-intercept.

y=-4/7x + 9 is already in that form.

A is not the answer because the y is supposed to be by itself.
B is not the answer because again, the y is not by itself.
C is not the answer because the y is also not by itself.

In the slope-intercept form, the y must be by itself and the slope (mx) and the y-intercept must be on the other side.

Hope this helps.
