Answer:
1)
<u><em>k - 5 = m</em></u>
<u><em>n - 3 = s</em></u>
2)
<u><em>Lisa is 17 and Myra is 12</em></u>
__________________________________________________
<u><em>1) </em></u>Key:
brother = b
me = m/n
sister = s
Equation:
m + 5 = b
m - 3 = s
Answer:
b - k = m
n - 3 = s
<u><em>2)</em></u>
L + M = 19
(L + 5) + M = 29
(L + 5 - 5) + m = 24
L + M = 24 / 2 = 12
L = 12 + 5 = 17
M = 12
Lisa will be 17 and Myra is 12
1/67 maybe -------------------
Answer:
-86
Step-by-step explanation:
simplify each equation as much as possible
f(x)= 4x(2+9) add
4x(11) multiply
f(x)=44x
substitute given numbers into each equation
44(-2)=-88 3(4)-14= 12-14=-2
combine equations
-88-(-2)= -86 add since you are subtracting a negative number
Answer:
Step-by-step explanation:
The most important part of this question is the estimation. That means you round either up or down to get whole numbers.
You can make - 37.44 either - 40 or - 35
You can make 4.8 into 5
So the answer should lie between -40/5 = - 8
or
The answer should be between - 35/5 = - 7
Use your calculator to check it.
-37.44 ÷ 4.8 = - 7.8
This skill is very handy when shopping or writing a test. It you get an outrageous answer like - 21.44 you know you have done something wrong.
Given:
i) 3, -5, -2, 1
ii) -1, -8, -7, -2
iii) -2, -4, 0, 2
To find:
increasing order of the given numbers.
Solution:
Increasing order: We need to start from the smallest number, then write larger number and end with the largest number.
We know that all negative numbers are less than the positive numbers and larger negative value is always the smaller one.
For example: -3 is less than -1.
i) We have,
3, -5, -2, 1
So, the increasing order of these number is -5, -3, -2, 1.
ii) We have,
-1, -8, -7, -2
So, the increasing order of these number is -8, -7, -2, -1.
iii) We have,
-2, -4, 0, 2
So, the increasing order of these number is -4, -2, 0, 2.
