Answer:
10
Step-by-step explanation:
5y + 2y -4y = 30
To solve first combine like terms
5y+2y-4y=3y
Then isolate your variable, do this by dividing both sides by 3.
3y=30
3y/3=30/3
Finally, simplify
y=10

If 3x+4=-5, what does x equal to?
First subtract 4 from both sides to isolate the 3x.
That leaves us with 3x = -9.
Since x is being multiplied by 3, to get x by itself,
we need to divide both sides of the equation by 3.
So our final answer is x = -3.
Answer:
x = -3
Step-by-step explanation:
3x + 4= -5
Subtract 4 from both sides.
3x = -9
Divide both sides by 3.
x = -3

Step-by-step explanation:
Answer:
25[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplifying the radicals
[tex]\sqrt{98}[/tex] = [tex]\sqrt{49(2)}[/tex] = [tex]\sqrt{49}[/tex] × [tex]\sqrt{2}[/tex] = 7[tex]\sqrt{2}[/tex]
[tex]\sqrt{32}[/tex] = [tex]\sqrt{16(2)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{2}[/tex] = 4[tex]\sqrt{2}[/tex]
Thus
3[tex]\sqrt{98}[/tex] + [tex]\sqrt{32}[/tex]
= 3(7[tex]\sqrt{2}[/tex] ) + 4[tex]\sqrt{2}[/tex]
= 21[tex]\sqrt{2}[/tex] + 4[tex]\sqrt{2}[/tex]
= 25[tex]\sqrt{2}[/tex]

Simplify: (-2x)4 help me with this!
The simplification of the given equation [tex](-2x)^4[/tex] is [tex]16 * x^4[/tex].
Exponents are mathematical notation used to indicate repeated multiplication of a number or expression by itself.
They are written as superscript numbers or symbols placed to the right and slightly above the base number or expression.
To simplify (-2x)^4, you can apply the power rule for exponents.
(-2x)^4 can be expanded as follows:
(-2x)^4 = (-2)^4 * x^4
Now, evaluate the exponent of the base -2 and x:
(-2)^4 = 16
Thus, the simplified expression is: [tex](-2x)^4 = 16 * x^4[/tex]

B. 2 x [tex]10^{4}[/tex] < 20,000
C.-74.308 < -0.74 x [tex]10^{3}[/tex]
D. 12,000,000 = 1.2 x [tex]10^{7}[/tex]
Step-by-step explanation:
let express them in the same form
5.3*1/100=0.053>-0.053 so A is false
2*10^4=2*10000=20,000 is equal to 20,000 so even B is false
-0.74*10^3=-0.74*1000=-740<-74.308 so even C is false
lets see D
1.2*10^7=12*10^6=12*1000000=12,000,000 which is equal to 12,000,000 so D is true
