5=3y+4x
Re write the statement 19+7 divided by 2-5 by including one pair of brackets to make the total equal to 8
3x + 2y = -9
X – Y = -13
Answer:
x =-7. .y=6
Step-by-step explanation:
3x + 2y = -9
(X – Y = -13)×3
3x + 2y = -9
3x – 3y = -39
5y = 30
y=6
3x +2(6)=-9
3x=-21
x=-7
3. Order each set of integers from least to greatest
a. 65, 61, 59, 45,2
b. 32, 78, 48, 33, 11
c. 99,86,5,63, 31,9
d. 79, 91, 32, 27, 20
5,15,35,65 solve the rule and the next term
Answer:
105
Step-by-step explanation:
Given the sequence of numbers
5,15,35,65
First lets get the common difference
d1 = 15-5 = 10
d2 = 35 - 15 = 20
d3 = 65-35 = 30
We can see that the differences form an arithmetic sequence
10, 20, 30..
Let's get the next term fist
Tn = a + (n-1)d
T4 = 10+(4-1)(10)
T4 = 10 + 3(10)
T4 = 10+30
T4 = 40
This means that the next term of the original sequence will be gotten by adding 40 to the preceding value
Next term = 65 + 40
Next term = 105
Hence the next term is 105
A.) 15.7in
B.) 31.4in
C.) 40in
D.) 62.8in
Answer:
31.4 in
Step-by-step explanation:
This is a tricky question,
if you observe the shape carefully, you will notice that if you mirror (flip outward) each curve surface of each quardrant, what you will end up with is a complete circle with a radius of 5 inches.
Hence the combined length of all the curved surfaces is simply the circumference of the circle, given by:
Circumference = 2πr
= 2 x 3.14 x 5
= 31.4 in
Consider the figure below.
What are the values of x and y?
Answers:
x = 14
y = 14
==========================================
Explanation:
The tickmarks indicate the sides x and y are the same length.
So y = x or x = y
We can use the Pythagorean theorem to say
a^2 + b^2 = c^2
x^2 + y^2 = (14*sqrt(2))^2
x^2 + x^2 = 14^2*(sqrt(2))^2
2x^2 = 196*2
x^2 = 196 ...... divide both sides by 2
x = sqrt(196)
x = 14
This must mean that y = 14 as well.
This triangle is an isosceles right triangle. We also consider it a 45-45-90 triangle because the three angles are 45, 45, and 90 degrees.
For any 45-45-90 triangle, the hypotenuse is always sqrt(2) times the leg length.
hypotenuse = leg*sqrt(2)

Answer: \frac{2}{5} ; or, write in decimal form: 0.4 .
Step-by-step explanation:
Rewrite as:
_______________________
[tex]\frac{4x}{7} = \frac{8}{35}[/tex] ;
________________________
Now, "Cross-factor multiply":
that is:
_____________________
→ Given: [tex]\frac{a}{b} =\frac{c}{d}[/tex] ;
→ ad = bc ; (b≠0 ; d≠0) ;
_____________________
As such:
4x * 35 = 7 * 8 ;
_______________________
We can divide one side of the equatiuon by "4" ; and one side by "7" :
[tex]\frac{4x*35}{4*7} = \frac{7*8}{4*7}[/tex] ;
_______________________
We can simplify the "left-hand side":
"4/4 = 1 " ; and "35/7 = 5 " ; & we are left with "x * 5" ; or "5x " .
________________________
We can simplify the "right-hand side":
"7/7 = 1 " ; and: "8/4 =2 " ; to get: "2/1" ; which equals "2".
_________________________
So; we have: " 5x = 2 " ; Solve for "x" ;
__________________________
Divide each side of the equation by "5" ; to isolate "x" on one ide of the equation; & to solve for: "x" ;
__________________________
" 5x/5 = 2/5 " ; We cancel out the "5x/5" to "1x"; which equals "x":
→ x = [tex]\frac{2}{5}[/tex] ; or, write in decimal format: "x = 0.4" ;
___________________________
\frac{2}{5}

Answer:
[tex]x = 0.4[/tex]
Step-by-step explanation:
[tex]\frac{7}{4} x \frac{4}{7} = \frac{7}{4} x \frac{8}{35}[/tex]
Reduce the number with the greatest common factor 7
[tex]\frac{1}{4} x 4x= \frac{7}{4}x\frac{8}{35}[/tex]
[tex]x=\frac{7}{4}x\frac{8}{35}[/tex]
[tex]x=7x\frac{2}{35}[/tex]

A group of students formed a circle during a game.
The circumference of the circle was about 43.96 ft. ,
and the diameter of the circle was 14 ft.
Which expression best represents the value of π?
Answer and Step-by-step explanation:
C = circumference = 43.96
d = diameter = 14
C = [tex]\pi d[/tex]
Divide both sides by d.
[tex]\frac{C}{d} = \pi[/tex]
[tex]\frac{43.96}{14}[/tex] = [tex]\pi[/tex]

72 is 25% of students that have a cat, how many total students are there?
Answer:
288
Step-by-step explanation:
1. Use the formula: P*T=N
P = percent, T = Total, and N is the other number.
2. So, P*T=N, therefore, 25%*T=72
3. Simplify .25*T=72
4. So get the Total (T) by itself, you have to divide both sides by .25
5. T = 72/.25
6. 288
