It can be: 2.5x-y+10 = 0
It is difficult to say when some of the signs are invisible.
The standard form for a linear equation is 2.5x - y + 10 = 0
.25x+3=10 .25x=7 25x=700 x=28
-15
This is a quadratic equation in the form of: 52 - 25x + 30 = 0 Solve by using the quadratic equation formula: x = 2 or x = 3 Or by factorising: (5x-10)(x-3) = 0, which means that x = 10/5 or x = 3
To solve the equation ( 25x + 2 = 5^{10} ), first, isolate ( 25x ) by subtracting 2 from both sides: ( 25x = 5^{10} - 2 ). Next, divide both sides by 25 to find ( x ): ( x = \frac{5^{10} - 2}{25} ). You can simplify ( 5^{10} ) as ( 25 \times 5^8 ), and then simplify the fraction further if needed.
To write the sum of the numbers 2,000,000,000 plus 70,000,000 plus 100,000 plus 70,000 plus 3,000 plus 800 plus 10 in standard form, first add them up: 2,000,000,000 + 70,000,000 + 100,000 + 70,000 + 3,000 + 800 + 10 equals 2,077,070,810. In standard form, this is written as ( 2.077070810 \times 10^9 ).
-4 plus 10 equals 6.
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
x=10
(5x + 10)(x + 3) or 5. (x + 2)(x + 3) Check with x = (say) 3 so 5 x 5 x 6 = 150; 45 + 75 + 30 = 150 OK
12 + 10 + 11 equals 33
-10 plus 10 equals 0.
