(PLEASE ANSWER FOR BRAINILEST ASAP!!) (EXPLAIN!!) 3 boxes all way the same amount. All together they weigh 54.3 pounds. How much does 1 box weigh?
Answer:
Step-by-step explanation:
Let B = the weight of box B
Let 2B = the weight of box A
Let 2B + 30 = the weight of box C
B + 2B + 2B + 30 = 640
5B = 610
B = 122 pounds, weight of box B
2B = 2(122) = 244 pounds, weight of box A
2B + 30 = 2(122) + 30 = 274 pounds, weight of box C

Mary bought 5 pairs of gloves and 2 hats for $95. Mary received a text from her friend Joanna ask her to buy 4 pairs of gloves and a hat. Mary told Joanna that the cost was $70. How much does each pair of gloves cost? How much does the hat cost?
Answer: Each pair of gloves costs $15 and each pair of hat costs $10.
Step-by-step explanation:
Let x = Cost per pair of gloves
y= Cost per hat.
As per given, we have
[tex]5x+2y=95 \ \ \ \ (i)\\4x+y=70\ \ \ \ \ (ii)[/tex]
Multiply (ii) by 2 , we get
[tex]8x+2y=140\ \ \ \ (iv)[/tex]
Eliminate (i) from (iv), we get
[tex]3x=45\\x=15[/tex]
Put this in (ii), we get
[tex]4(15)+y=70\\60+y=70\\y=10[/tex]
Hence, each pair of gloves costs $15 and each pair of hat costs $10.

1st one x=245°
2nd one x= 250
Step-by-step explanation:
hope its correct
hope u find it helpful
Answer:
x = 245 and x = 20
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 , then
sum = 180° × 3 = 540°
Sum the interior angles and equate to 540
25 + 112 + 100 + 58 + x = 540
295 + x = 540 ( subtract 295 from both sides )
x = 245
---------------------------------------------------------------
5x + 2 + 3x + 5 + 8x + 8 + 4x + 15 + 5x + 10 = 540
25x + 40 = 540 ( subtract 40 from both sides )
25x = 500 ( divide both sides by 25 )
x = 20
in triangle ABC with vertices A(4,5),B(-2,1) and C(0,3),E and F are midpoints of sides AB and AC resp . then, find coordinates of E and F
Answer:
The answer is
E=(1, 3)
F=(2,4)
Step-by-step explanation:
When E is midpoint of AB
Then
[tex]e = ( \frac{4 + ( - 2)}{2} . \frac{5 + 1}{2} ) \\ = (1.3)[/tex]
By this way we can find F
[tex]f = ( \frac{4 + 0}{2} . \frac{5 + 3}{2} ) \\ = (2.4)[/tex]

If she pays with a £20 note, how much change would she get in pounds, £?
I’ve been stuck on this for a few minutes. I’m not really sure what to do..
Answer:
Step-by-step explanation:
You know that the three angles of a triangle add up to 180°. If one angle is 38° and another angle is 67°, then the third angle must be 180°-38°-67° = 75°.
You have a straight line across the bottom, and three angles meeting in the middle of it. Those three angles add up to 180°. One of them is 75°, another is 50°, so the third angle must be 180°-75°-50° = 55°.
That leaves you with one unknown angle. ? = 180°-40°-55° = 85°

**please let me know if this was wrong**
Answer:
1) In the second step, it was supposed to multiply 9 and 2 and 36 by 3 instead of adding 9 and 3 to each other because multiplication and division comes before adding, according to pemdas.
2) In the second step, they were supposed to multiply 6 and 4 instead of subtracting 27 and 6 because multiplication comes before subtraction, according to pemdas.
3)
(43 - 20) - 2 · 5
43 - 20 = 23
23 - 2 · 5
2 · 5 = 10
23 - 10 =
13
4) 81 ÷ (13 - 4)
13 - 4 = 9
81 ÷ 9
81 ÷ 9 =
9
5) 7 · 8 - 3 · 6 + 1
7 · 8 = 56
3 · 6 = 18
56 - 18 + 1
56 - 18 = 38
38 + 1 =
39
6)
7)
8)
Step-by-step explanation:
Section 1: Explain the error in each problem below.1) Pemdas says multiplication and division comes before adding, so you must solve the multiplication in the problem first before the addition.
2) Again, as pemdas says, multiplication comes first before subtraction, so you must solve the multiplication in the problem first before the sutraction.
Section 2: Simplify the following expressions.3) (43 - 20) - 2 · 5
Pemdas says to solve the parenthesis first.
43 - 20 = 2323 - 2 · 5Now multiplication comes next (because there's no exponents).
2 · 5 = 1023 - 10Now subtraction.
23 - 10 = 134) 81 ÷ (13 - 4)
Pemdas says to solve the parenthesis first.
13 - 4 = 981 ÷ 9Now division comes next.
81 ÷ 9 = 95) 7 · 8 - 3 · 6 + 1
Pemdas says to solve the multiplication first.
7 · 8 = 56 3 · 6 = 1856 - 18 + 1Now subtraction and addition.
56 - 18 = 3838 + 1 = 396)

Did you type the question wrong?
Step-by-step explanation:
1.5 is the less that 16 that why it is the mixed fraction
solve by substitution y - 3x = 2, x - 2y = -6
y=2+3x
putting value on second equation we get..
x-2(2+3x)=-6
x-4+6x=-6
7x=-2
×=-2/7
& y=2+3(2/7)
y=2+0.87
y=2.87..Ans..
Answer:
x= 2/5
y= 3.2
Step-by-step explanation:
y-3x=2
y=3x+2
replace y with 3x+2 in second equation;
x-2(3x+2)= -6
x- (6x+4)= -6
x-6x-4= -6
-5x-4+4=-6+4
-5x= -2
x= 2/5
y=3x+2
y=(3×2/5) +2
y= 3.2

Solve the simultaneous equations
5x + 3y = 41
2x + 3y = 20
Do not use trial and improvement
The solution to the system of equation is (7, 2)
Using the simultaneous equation:
5x + 3y = 41
2x + 3y = 20
using elimination method
Subtract equation 1 from 2 to have:
5x - 2x = 41 - 20
3x = 21
x = 21/3
x = 7
Substitute x = 7 into equation 1 to get y
5x + 3y = 41
5(7) + 3y = 41
35 + 3y = 41
5y = 41 - 35
3y = 6
y = 6/3
y = 2
Hence the solution to the system of equation is (7, 2)
