Answer:
67
Step-by-step explanation:
subtract 90 from 23 and you should have what you need to save.
X=weekly allowance
x/2=money saved (= money spent).
We can suggest this equation:
x/2+4=12
lowest common multiple=2
x+8=24
x=24-8
x=16
Answer: her weekly allowance is $16.
Answer:
12
Step-by-step explanation:
Answer:
b=15 g=25
Step-by-step explanation:
lets translate that story problem to mathematics equations
the problem told that no. of girls are 10 more than no of boys so this will =
g=b+10
then in class there are 40 students that means
g+b=40
now we have to equations with two variables then we should substitute
(b+10)+b=40
lets remove the brackets
2b+10=40 subtract 10 from both sides
2b=30 now divide both by 2
b=15 so g=25 after you write the equation once again with the new proof or number
Answer:
5, 2x2 and 4
Step-by-step explanation:
Terms are expressions or characters that are separated by a plus or minus sign.
therefore, the terms are 3x, 5, 2x2 and 4
like terms have the same have the same variables or no variables attached to them.
like terms = 5, 2x2, and 4
Note: 2x2 = 4
