x/2+21=45
what is x in this equation?
Answer:
x = 48
Step-by-step explanation:
x/2+21=45
subtract 21 on both sides
x/2 + 21 - 21 = 45 - 21
x/2 = 24
Multiply by 2 on both sides
x/2 * 2 = 24 * 2
x = 48
Check
48/2 + 21 = 45
24 + 21 = 45
45 = 45 CORRECT
Hope this helped!

Answer:
7 is the answer
Step-by-step explanation:
They are based on 7th hrs.
Answer:
7
Step-by-step explanation:
If
4=28
Then let 1 be = x
so;
4=28
1=x
x=¼×28
x=7
This is because 28 can be divided by 4, 7 times.
-3x + 4y = 24
4x - y = 7
Answer:
y=7-4x/-1
y=-7+4x
substituting y=-7+4x
-3x+4(-7+4x)=24
-3x-28+16x=24
-3x+16x-28-24=0
13x-52=0
13x=52
x=52/13
x=4
substituting x=4
-3x+4y=24
-3(4)+4y=24
-12-24+4y=0
-36+4y
4y=36
y=36/4
y=9

If I multiply a number L by another number M, I get 452,199. If I multiply L by the successor of M, I get 454,322. Find L x L.
plz tell the answer fast plz in is urgent :)
Step-by-step explanation:
L * M = 452,199
L * (M + 1) = 454,322
Therefore L * (M + 1) = L * M + L.
=> 454,322 = 452,199 + L, L = 2,123.
Hence L² = 2,123² = 4,507,129.

Step-by-step explanation:
4. Each unlabelled opposites are positioned at a 0.5 interval. That means each division in between 0 and 1, 1 and 2, 2 and 3, 3 and 4 are 0.5. So we have 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4
Same idea is applicable on the negative side of the graph. We have 0, -0.5, -1, -1.5, -2, -2.5, -3, -3.5, 4.
5. Like 4 above, each unlabelled opposite is positioned at an 0.5 or 1/2 interval.
So we have, 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4 (for the positive side) and 0, -0.5, -1, -1.5, -2, -2.5, -3, -3.5, 4 (for the negative side).
6a.
A positive number is one greater than zero while a negative number is one lesser than zero. So we have -0.5 and 0.5
6b. -0.4, 0.4
6c. -3.5, -3 1/2

The cost of polishing 35 identical wooden cubical boxes at the rate of rs. 20 per sq. cm is rs. 1,51,200. Find the edge of each cubical box
Answer: 6 cm
Step-by-step explanation:
Total surface area of cubical box = [tex]6a^2[/tex] , a= edge length of cube (i)
As per given ,
Total surface area of one box = [tex]\dfrac{\text{Cost of polishing}}{\text{Rate} \times\text{Number of boxes}}[/tex]
[tex]=\dfrac{151200}{20\times35}\\\\=\dfrac{151200}{700}\\\\= 216\ sq. cm[/tex] (ii)
Now from (i) and (ii) ,
[tex]6a^2 = 216\\\\\Rightarrow\ a^2= 36\\\\\Rightarrow\ a= 6 \text{ [By taking square root on both sides]}[/tex]
Hence, the edge of each cubical box = 6 cm.
CAN SOMEONE HELP ME I’LL GIVE OUT BRAINLIEST THANK YOU
Answer:
112.5 miles.
Step-by-step explanation:
2 cm = 25 miles
The question is asking you for the distance between two cities, and is giving you the information that it's 9 cm on the map.
2 cm + 2 cm + 2 cm + 2 cm = 8 cm
25 divided by 2 is 12.5, which would give you 1 cm for the map key.
2 cm + 2 cm + 2 cm + 2 cm + 1 cm = 9 cm
25 miles + 25 miles + 25 miles + 25 miles + 12.5 miles = 112.5
PLEASE HELP HERES CONTEXT FOR THE WORK PLEASE PLEASE HELP: ROSEMARY HONEY VEGAN BREAD RECIPE
(makes 2 loaves)
Ingredients:
1 package (% oz.) of active dry yeast
2 % cup of warm water (110-115 degrees)
O3 Tbsp. of sugar
1-2 teaspoons of Rosemary
1 Tbsp. of salt
2 Tbsp. of Canola Oil
6 4 cups of flour
½ Tbsp. of honey
Preheat oven to 3?5 degrees. In a large bowl add the yeast. Next add the warm water
and watch for the bubbles to form.
Then add your sugar, Rosemary, salt, Canola Oil, and flour. Start to knead your dough
(work the dough with your hands). Form a ball with the dough. Add honey, and nead
the bread some more. The more you knead the dough, the more light and fluffy the
bread wll be beoause this forms more air pockets. I learned this because with my first
batch of bread it turned out very dense. It was still very yummy, but it is much better
if you take extra time and knead the bread so that it is aíry.
Place in bowl and cover. You will let the dough sit for 1 ½ to rise. This is called
proofing. You will notice that the plastic wrap will get foggy. This is okay, and you are
on your way. The dough should rise almost twice its size.
Next, use vegan butter to coat your pan so that your bread does not stick. Form your
bread shape and place in the oven for 30-35 minutes. Set your timer. I always check
mine at 25 minutes, just to see how it is doing. You can turn on the light in your oven
and peek through the oven window. I also noticed that the bread cooking made our
apartment smell really nice and cozy. Bread is a comfort food. When the bell rings, use
your oven mitts or have an adult to remove the bread from the oven. Let cool down for
15-20 minutes. Slice, add butter or jam, and serve to those you lovel
Answer:

Could someone help me find the possible THIRD SIDE to the triangle if two sides are given.
1. 4cm, 17cm
2. 24ft, 52 ft
3. 9yd, 33yd
4. 16km, 17km
Answer: ↓↓↓
Step-by-step explanation:
1. 13 < x < 21
2. 28 < x < 76
3. 24 < x < 42
4. 1 < x < 33
To find the number behind the x, just find the difference between the two numbers but make sure it's positive. Finding the number in front of the x, you add the two numbers together. X has to be greater than the smaller number but less than the greater number because to make a triangle, if two sides are added, their sum should be greater than the third side.
Hope that helped!

7 plus the sum of a number x and 5 simplified expression:
Answer:
7+(x+5) (original equation)
x+12 (simplified)
Step-by-step explanation:
So we know the number is x
Since its just an expression we can’t make x equal to anything so the best we can do is simplify the expression given.
so 7 plus the sum of x and 5
7+(X+5)
Mow just simplify it
x+5 is x+5
x+5+7 is 12+x becuase 5+7 is 12 and I combined like terms
x+12
Answer:
Expression: 7+x+5
Simplified: 12+x

What type of correlation/association exists?
The number of hours you sleep in and the number of hours you are awake during the day
Answer:
Negative Correlation
Step-by-step explanation:
there is a negative correlation between the number of hours you sleep in and the number of hours you are awake during the day as the longer you are either awake or asleep the less time you will be doing the other thing
Here is a graph I made that will hopefully help you understand.
Even if I switched around the label for the x or y-axis, the correlation would still remain the same because the more you stay asleep, the less you will be awake and vice versa.
what is the area of the shape
Answer:
A= 18
Step-by-step explanation:
To find the height, find the blocks inside the shape that is completely attached (they have to be in a straight vertical line). In this case, you can see that three vertical blocks in the middle of the shape is completely attached. That means your height is 3.
To find the width, look at the how many horizontal boxes make up the top. 6 block inside the shape corispond with 6 blocks on top of the shape, so the width is six.
Multiply 6 by 3 to get 18.

Which expression is equivalent to-g-7+3g-6
given m and n find the value of x
Answer:
x = 18
Step-by-step explanation:
you can create the following equation to solve for x:
5x - 2 + 5x + 2 = 180
10x = 180
x = 18
Which equation has the same solution as x2 - 6x - 14 = 0?
Answer:
B
Step-by-step explanation:
Given
x² - 6x - 14 = 0 ( add 14 to both sides )
x² - 6x = 14
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = 14 + 9
(x - 3)² = 23 → B
