Answer:
x = -5
y = 20
Step-by-step explanation:
3x + y = 5
3x - 3x + y = 5 - 3x
y = 5 - 3x
--------------------------------------------------------
4x + 2y = 20
4x + 2(5 - 3x) = 20
4x + 2(5) + 2(-3x) = 20
4x + 10 - 6x = 20
10 - 2x = 20
10 - 10 - 2x = 20 - 10
-2x = 10
-2x ÷ -2 = 10 ÷ -2
x = -5
--------------------------------------------------------
y = 5 - 3x
y = 5 - 3(-5)
y = 5 + 15
y = 20
How many moles is 1.46 g of hydrogen gas
The number of moles is 1.4484 moles
What is one mole?
The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12
The 6.022 x 10²³ number is known as the number of Avogadro or the constant of Avogadro.
(12 g C = 1 mol C atoms = 6.022 × 10²³ C atoms)
Given data ,
Grams of Hydrogen = 1.46 grams of Hydrogen
Now , 1 g of Hydrogen has 0.99212 mole
So , to calculate the number of moles in 1.46 grams of Hydrogen =
Grams of Hydrogen x 0.99212 mole
The number of moles in 1.46 grams of Hydrogen = 1.46 x 0.99212
= 1.4484 moles
Hence , the number of moles in 1.46g of Hydrogen is 1.4484 moles

PLEASE HELP! ITS A DECENTLY EASY QUESTION BUT I CANT FIGURE IT OUT!
Answer:
3,4 and 5 are correct........☺
Answer:
3,4,5
Step-by-step explanation:
To answer, we must go through all the expressions shown, solve them, and make sure that they are exactly like 3xy + 6yz.
1. We must distribute 3 to whatever is in the parentheses, but if you look, you can see that we have to multiply 3 by 6yz, which would come out to 18yz, and that is not in the original expression, so this one is FALSE
2. For this expression, we can rule it out because the first part of the expression would be 3xyz, and that is not a part of the original expression, this is one is FALSE
3. This expression, if you distribute the 3y, you get 3yx + 6zy, which is the same as the original expression, even if the variables are a bit jumbled, they all have the same value, so this one is TRUE
4. If you distribute y for this expression, you get y3x + y6z, which is the same as the original expression, because as I said before, the variables can be jumbled, but as long as all the values are there, we can safely say that this expression is TRUE
5. As you can see, this expression is the same as 4, so this one is also TRUE
Hope this helps :)

The length of a rectangle is 3cm more than its width.If the area of the rectangle is 28cm^2,find the width.
Answer: The dimensions of the rectangle are 7 cm × 4 cm
Step-by-step explanation:
let,
Breadth of the rectangle (l) = x
Length of the rectangle (b) = x + 3
Area of the rectangle = 28 cm²
Area of the rectangle = l × b
⇒ (x) × (x + 3) = 28
⇒ x² + 3 x = 28
⇒ x² - 3 x - 28 = 0
⇒ x² - 7 x + 4 x - 28 = 0
⇒ (x - 7) + 4(x - 7) = 0
⇒ (x - 7)(x + 4) = 0
⇒ x = 4
Breadth = 4 cm
Length -
⇒ 4 + 3
⇒ 7 cm

Answer:
p=4.9
Step-by-step explanation:
Answer:
4.9
Step-by-step explanation:
[tex]2.5 + 3(5 - 2.1p) = - 13.37[/tex]
1) Open the brackets by multiplying 3 with each term present inside the bracket.
[tex] = > 2.5 + 15 - 6.3p = - 13.37[/tex]
2) Add the constant teems present in left-hand side.
[tex] = > 17.5 - 6.3p = - 13.37[/tex]
3) Take 17.5 to right-hand side by changing its sign from positive to negative.
[tex] = > - 6.3p = - 13.37 - 17.5[/tex]
[tex] = > - 6.3p = - 30.87[/tex]
4) Take -6.3 to right-hand side by dividing -30.87 by --6.3.
[tex] = > p = \frac{ - 30.87}{ - 6.3} = 4.9[/tex]

¿Qué peso transporta una tractomula que lleva 134 bultos de trigo de 62 kilos cada uno, 28 sacos de café de 50 kilos cada uno y 37 bultos de arroz de 75 kilos cada uno?
Answer:
the total weight is 12,483 kilos
Step-by-step explanation:
The computation of the weight is shown below:
Wheat = 134 × 62 = 8308
Coffee = 28 × 50 = 1400
Rice 37 × 75 = 2775
Total weight is
= 8308 + 1400 + 2775
= 12,483 kilos
Hence, the total weight is 12,483 kilos

What are the factors of -36 that will sum to give you a -5?
Answer:
4, and -9
Step-by-step explanation:
Well, to solve this problem, lets first list all the factors of -36.
-36 = 1*(-36)
-36 = 2 * (-18)
-36 = 3 * (-12)
-36 = 4 * (-9)
-36 = 6 * (-6)
-36 = 12 * (-3)
-36 = 18 * (-2)
-36 = (-36) * 1.
So, we can see that 4 + (-9) = -5.
(05.02) In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angle.
A straight line is shown and is marked with three angles. The first angle measures 50 degrees. The second angle measures 40 degrees. The third angle is labeled x. The line between the 40 degree angle and angle x extends below the straight line. The angle formed is labeled angle y.
Write and solve an equation to determine the measure of angle y.
☁️My Answer☁️:
y = 90°
✧My Step-by-step explanation✧:
The angle x forms a straight line with the both the 50° angle and the 40° angle:
x + 50° + 40° = 180°
x = 90°
Which means…
y = x = 90°
Find the value of in the triangle shown below.
Step-by-step explanation:
in isoscles triangles two angles and lengths are equal .
two sides equal 3.5
so both of the angles are 55°
the sum of the angles in a triangle is 180°, so
x = 180° - 55° - 55°
x = 70° (Ans)
Hannah and her friend are training to run in a 2-mile race. On Monday, Hannah ran ½ mile. On Tuesday, she ran ⅕ mile farther than she ran on Monday.
a. How far did Hannah run on Tuesday?
b. If her friend ran ¾ mile on Tuesday, how many miles did the girls run in all on Tuesday?
Answer:
A: Hannah ran 0.7 miles on Tuesday
B: They ran 1.45 miles in total
Step-by-step explanation:
If you put all the fractions into decimal form it would be;
1/2 = 0.5
1/5 = 0.2
3.4 = 0.75
So, you add all of the decimals together;
0.5 + 0.2 = 0.7
0.7 + 0.75 = 1.45
