Answer:
HJ = 17
IK = 30
Step-by-step explanation:
to find HI :
GH : 2
HI : ?
IJ : 12
GI : 7
HI = GI - GH
HI = 7- 2
HI = 5
HI + IJ = HJ
5 + 12 = HJ
17 = HJ
To find IK
IJ = ?
JK = 12
KL = ?
IL = 49
JL = 31
To find IK we need to find KL and IJ
KL = JL - JK
KL = 31 - 12
KL = 19
IJ = IL - (JK + KL)
IJ = 49 - 31
IJ = 18
IK = IJ + JK
IK = 18 + 12
IK = 30
Answer:106
Step-by-step explanation:
Let number of white marbles be w
Let number of red marbles be r
w+r = 126---------1
w = 6 +5r-----------2
Put eqn 2 in eqn 1
6+ 5r + r = 126
6 + 6r = 126
6r = 120
r = 20
w = 6 +5r =6+100
= 106
Answer:
the cost of a liter of milk is $0.75
the cost of a loaf of bread is $1.75
Step-by-step explanation:
Let
x------> the cost of a liter of milk
y------> the cost of a loaf of bread
we know that
------> equation A
------> equation B
Multiply equation A by
-------> equation C
Multiply equation B by
------> equation D
Adds equation C and equation D
Find the value of x
substitute the value of y in the equation A
Answer:
2 dollars
Step-by-step explanation:
5% interest is 1.05
1.05 times 40 equals 42
42-40 equal 2
So 2 dollars
Order them from smallest to largest:
21, 24, 25, 26, 26, 31
mean: 25.5
add all the numbers up and divide them by 6.
median: 25.5
the number in between 25 & 26.
mode: 26
there are two 26’s in the pattern.
range: 21-31
