You have to do $1,790 reduced (decreased) by $395 times 800 and your answer is $1166,000
There’s an invisible 1 in front of the minus sign and an invisible 1 in front of the variable.
-1(r+4)=-3 —> -1 times 1r = -1r. -1 times 4 = -4
Multiply inside the parentheses.
-1r-4=-3
Now add 4 to both sides.
-1r-4=-3
+4=+4
-1r = 1
Now divide
R= -1
Answer:
B, C, E are true
Step-by-step explanation:
A = l*w
The original rectangle is 6 by 4 with A = 24
The 1st enlargement = 6*3 by 4*3
18 by 12 with A = 216
The second enlargement is 18*3 by 12*3
54 by36 with A =1944
A.The area of the first enlargement is 72 square inches.
False it is 216
B.The area of the second enlargement is 1,944 square inches.
True
C.The area of the second enlargement is (3 squared) squared times the original area.
216/24 =9 True
D.The area of the second enlargement is 3 times the area of the first enlargement.
1944/24 = 9 False
E.The ratio of the area of the first enlargement to the area of the original equals the square of the scale factor.
The scale factor is 3 3^2 =9 216/24 =9
True
8+12+4= 24
This is the total amount of marbles. You’ll divide the green marbles by the total amount since you want the probability of green marbles.
4/24= .16 or 16% possibikity
