Answer:
24
Step-by-step explanation:
Let's see the factor pairs of 60 first.
1,60
2,30
3,20
4,15
5,12
6,10
10,6
12,5
15,4
20,3
60,1
1,60 and 60,1 is not possible for xy1 and 1xy. It is because any one digit*one digit=not 60. The remaining pairs are...
2,30
3,20
4,15
5,12
6,10
10,6
12,5
15,4
20,3
30,2
Next, start with 2,30 and 30,2
The one digit factor pairs of 30 is 5 and 6.
So...
256 is possible
265 is possible
562 is possible
652 is possible
3,20
4,15
5,12
6,10
10,6
12,5
15,4
20,3
+4
Next, 3,20 and 20,3
20=4*5
453,543,345,354
4,15
5,12
6,10
10,6
12,5
15,4
+8
4,15 and 15,4
4 number that are possible(5*3=15)
5,12
6,10
10,6
12,5
+12
5,12 and 12,5
3,4 and 2,6
526,562,534,543,435,345,265,625
6,10
10,6
+20
10=5*2
+4
20+4=24

Answer:
y = -7
Step-by-step explanation:
To answer this question, we must first plug in -8 for x:
3(-8) + 5y = -59
-24 + 5y = -59
+24 +24
5y = -35
/5 /5
y = -7
Hope this helps :)
Answer:
<h2>Y = 22.56 cm </h2>
Step-by-step explanation:
To find the diameter Y of the circle we must first find the radius of the circle
Area of a circle = πr²
where
r is the radius
From the question
Area = 400cm²
Substitute the value into the above formula and solve for the radius
That's
400 = πr²
Divide both sides by π
We have
Find the square root of both sides
radius = 11.28 cm
Since we have the radius we can use it to find the diameter Y using the formula
diameter = radius × 2
radius = 11.28
Y = 11. 28 × 2
We have the final answer as
<h3>Y = 22.56 cm</h3>
Hope this helps you
9^1/3 * 3^x = 27^4/5
Rewrite 9 as 3^2
(3^2)^1/3 * 3^x = 27^4/5
Multiply the exponents in the first term:
3^2/3 * 3^x = 27^4/5
Use power rule to combine exponents:
3^(2/3 +x) = 27^4/5
Rewrite the 2nd term:
3^(2/3 +x) = (3^3)^4/5
Set the exponents only to equal:
2/3 + x = 3(4/5)
Solve for x:
simplify the right side:
2/3 + x = 12/5
Subtract 2/3 from both sides:
x = 26/15
X is less than or equal to -3
explanation
first, i added 6x to both sides
next, i subtracted 25 from both sides
then i divided by 14 and got -3
