Where’s my smart friends??
I had $3.00.
My Mom gave me $10.00.
My Dad Gave me $30.00.
My Aunt & Uncle gave me $100.00.
I had another $7.00.
How much did I have?
Answer:
$10 Its asking how much you had not how much was given to you. So the answer is you had 10
I have $150
In order to determine the amount you have, add the amounts you are given to the original amount. This is because the money you have increases by the amounts you are given
Total sum of money = amount you have + amount given by mum + amount given by dad + amount given by uncle and aunt
$3 + $10 + $30 + $100 + $7 = $150

A video store charges $12 for used games and $25 for new games. Jonathan has saved $300 to spend on video games. X=number of used games y=number of new games which linear equation, written in standard form, expresses the scenario?
Answer:
12x+25y=300.
he can buy 25 used games .hope this helped!
Answer:
12x+25y=300
Step-by-step explanation:
Standard Form= Ax+Bx=C
12x, because $12 for each old video game (x) he gets.
25y, because for each new game (y) it costs $25.
total=300

Answer:
angles BED and DEA, and angles AEC and BEC are supplementary angles
Step-by-step explanation:
If you do not know what supplementary angles are, then just know that it means two angles added together that equal 180 degrees. So, all you need to do is find two angles on the picture that equal 180 degrees when added together.

Describe the relationship between integers and rational numbers.
Answer:
Integers are a subset of Rational Numbers because all Integers are Rational Numbers.
Step-by-step explanation:
Hope this helped mark me as brainliest (:
Answer: Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers
Step-by-step explanation:
write the first 4 terms of the arithmetic sequence With first term 37 and common difference 9
Answers:
first term = 37
second term = 46
third term = 55
fourth term = 64
==========================================
Explanation:
Start at 37. Add 9 to this term to get the second term. Add 9 to that result to get the next term, and so on.
first term = 37
second term = 37+9 = 46
third term = 46+9 = 55
fourth term = 55+9 = 64
-----------
The nth term formula is
a(n) = 9n+28
It can be found by plugging a = 37 and d = 9 into the general form
a(n) = a + d*(n-1)
The four terms of the arithmetic sequence with a first term of 37 and a common difference of 9 are: 37, 46, 55, and 64.
An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms remains constant.
Given:
First term (a1) = 37
Common difference (d) = 9
The arithmetic sequence can be represented as follows:
[tex]a_1[/tex]= 37
[tex]a_2[/tex] = [tex]a_1[/tex] + d
= 37 + 9 = 46
[tex]a_3[/tex] = [tex]a_2[/tex] + d
= 46 + 9 = 55
[tex]a_4[/tex] = [tex]a_3[/tex]+ d
= 55 + 9 = 64
So, the first four terms of the arithmetic sequence are: 37, 46, 55, and 64.

unknown numbers:
I think of a number, add seven, then divide by five.
Answer:
(x+7)÷5
Step-by-step explanation:
since the number is unknown, it becomes X. Because we first add 7 then divide by 5, the expression will be a bracketed (X+7), followed by the division by 5. This makes sense because of the BODMAS rule to which, in coherence with the BODMAS rule, we first solve the expression in the brackets then move on outside them.

Answer:
A) Positive (4, 2, 0), negative (0)
Step-by-step explanation:
Descartes' rule of signs tells you the number of positive real roots is equal to the number of sign changes in the coefficients (with allowance for an even number of roots possibly being complex).
The signs of the coefficients are ...
- + - + -
so there are 4 sign changes. The number of positive real roots will be 4, 2, or 0.
__
Changing the signs of odd-degree terms, you can use the same method to determine the number of negative real roots. With those signs changed, the signs of the coefficients are ...
- - - - -
so there are 0 sign changes. The number of negative real roots is 0.
_____
The graph shows there are no real roots of either sign. All the roots are complex.

To start we would resolve the absolute value of [tex]|-3|[/tex]. We know that absolute value is the distance from zero so it would be 3.
Our new equation is [tex]3+6/(4-1)*8[/tex]
Now we need to solve in the order of PEDMAS starting with parenthesis to get [tex]3+6/3*8[/tex]
Next in PEDMAS we have Division/Multiplication since we don't have any exponents. We do all the division and multiplication left to right so we would divide to get [tex]3+2*8[/tex] and then multiply to get [tex]3+16[/tex].
Finally, we only have addition left over so our answer would be [tex]19[/tex]
