$250,000 x 0.04 = 10,000 in addition to the original amount
Step-by-step explanation:
you make x the subject of formula for all the questions.
- a(x+b)=c
firstly you divide both sides of the equation by a, this way the a will cancel it self out of the equation
x+b= c/a
then you take '+b' to the other side of the equation over the = sign, this makes +b sign to change it then becomes -b
x=c/a -b
2. 7(x-a)=b
you divide both sides of the equation by 7.
x-a=b/7
then you take -a to the other side of the equation it becomes +a
x=b/7+a
<u>NOTE</u>: always eliminate the number/letter beside the bracket first. it unlocks the bracket. the number or letter is joined to a bracket by multiplication so we divide to eliminate it

Answer:
1176.679ft²
Step-by-step explanation:
<u>The question is on surface area of a cylindrical fuel tank</u>
Equation for surface area of a cylinder
S.A = 2
rh +2
r²
where r is the radius of cylinder and h is height of cylinder
Diameter=7'⇒r=3.5' and h=50'
Surface Area= 2×3.142×3.5×50 + 2×3.142×3.5×3.5
S.A=1099.7+76.979=1176.679ft²
Smith = 1.5Jones
S=1.5J
S + J = 15
1.5J + J = 15
2.5J = 15
J = 6
S = 9
